I used to wire boats in the Navy and found that boards like you put together are great. What i did different than you is I found that servicing things required I put the relays farther apart from the terminal block and the fuse block needed to also be farther away in order to service them quicker and more efficiently. I agree that it is more professional to make a panel and have things in a neat and proper order.

just learned more in 13 mins then I ever did in my basic electrical class.

This is exactly what i wanted to do to my car. Glad i found this easy install video. Right now i just have wires running all over with fuses inline cause i had no idea how to have a clean setup. Also that plastic is a great idea, i was looking into sheetmetal cause i wanted something to bolt my ecu on to as well as relays. Thanks for a great how to video.

WORK OF ART! my second day on this channel and i cant stop watching gets more and more interesting.👌nothing like a clean job. The breaker was a good tip.

I did something similar for my motorcycle and all the addons for it. I added another relay for the main power so the whole panel is switched to ignition switch in run position.... used a heaver power relay for that one. Well done!! Nice and compact. Variant to this would be getting ‘marine grade ‘ parts which are more water and corosion resistant... but more $$ too...

I have been all over the interwebs searching trying to figure out how to wire up a power windows conversion and add electronic door locks to my standard truck. thanks for the educational video.

I have to add that the way you've explained the relay process is so, so good. Clarified the mystic of relays. Thank you, well done.

Seriously so excited to have watched this video. I’m in the middle of my first engine swap where the engine didn’t come in the car I’m installing into, and I have been trying to understand how wiring works and how I’d get power to all of my stuff. Very thankful for this video. Btw I’m installing an engine from a 99’ slk230 Kompressor into a 1990 190e Mercedes

And thats why I watch this channel......Great work Thanks Don M

great video and very professional end product. If I might make two suggestions to improve the final outcome if only marginally, first I always use marine grade awg rated wire it is tinned copper and will not corrode in normal automotive use and only costs a few cents more. Second I use aviation style ratcheting crimpers they work much better and do not require soldering which will prolong your wiring life by not removing flexibility from the wire.

This is awesome. I'm about to get my automotive electrical done at school and I'm going be adding lights on my 4runner. I've only ordered one light and everything else to go with it so far. After watching this I'm leaning more towards this setup rather than just screwing the relay to the side of the fuse box that's already in my car. This also looks a lot better than just a fuse harness dangling about too. With this setup you can always add more if you have only one circuit going through it. Thank you for the video man! It looks great!

Fantastic video! You really were able to simplify what I consider to be very complicated. Your camera skills were spot on! Sound track was awesome! Thanks for making this vid!

Badass song and great (informative) video, thanks for both!

"The Force is strong with this one" thanks for that lesson keep'em coming!

This was probably the first video of your I watched maybe 5 years ago or longer. 1. You have come a long way! 2. I went into my garage today to start working on my car. 3. Its ok to make mistakes and learn as we go. Keep up the good work!

Very nice work! If you are controlling loads from an engine computer, very often it is the ground side that’s switched. That means having a low amperage power source to the white wire and bringing the black wire out to the appropriate computer harness location. For loads that you manually switch, this setup is perfect. Love the main circuit breaker advice, too. Great video, thanks!

That looks really good. Nice job - simple neat and cheap! I LIKE IT! Just one comment: it looks like your "heavy" wire is no bigger than AWG stranded #10 (?). That wire will most likely "burn" if it shorts out directly to ground between the 300A breaker and the fuse block . Based on the NEC, probably the breaker would be 80A or less to protect #10 if its about 4' from the breaker to the fuse box. At 300A you are talking about AWG #4.

First time subscribing after one video.. Great job

Just had surgery, made one for the drift car as a project to keep me sane while recovering. almost done just waiting on the relays some grommets and non insulated ring terminals (will be soldered, crimped and heat shrinked) to arrive to finish it. then the whole car is getting rewired. Keep up the great work man, the channel is awesome.

hey kyle I just have to say thank you! your videos are one of only 3 things keeping me going after my accident last year I have watched almost every video you have made twice now and you videos are amazing very informative and fun I hope to one day so similar to you and use you as a big influence in how I will do my work keep up the amazing work. this coming from a fellow fabricator

A little double sided tape works great for holding parts in place when determining placement and predrilling holes

Perfect Video! No "blah, blah, blah", no BS, clear, concise & straight to the POINT! Even went out of your way to list all parts needed to build this! What else could you ask for?! Thank You!! #AmeriCuh

Honestly one of the best DIY videos I have found on KZfaq. Thank you! Great job. Plus I found a new favorite song.

Brilliant video! This has answered loads of questions I've been trying to find in workshop manuals. Thanks, man!

Nice video. Highly appreciate the links to parts!

Really well done! Only suggestion for improvement would be to have had an actual switch to show one example with all the elements.

So glad I found this video! I'm about to completely rewire and modernize my 65 ambassador. This is going to be a big help for keeping it clean. Thanks!

You are amazing. Learned a great deal in just a short time. Will put it to use on my 67 Bonneville. There are just too few circuits for today's gadgets.Really need to upgrade. Thanks for sharing.

Awesome video. Thank you! I’ll be making one just like this to run my off road lights. Again, thank you for the knowledge. 👍

thanks for this video looks real good. looks like you know what your doing lol. love your videos I just found you about week ago now my recommendation is all your videos lol. also enjoy the music. keep up the work

I like the fact that you didnt edit out your mistake on the layout. I respect that, thanks for the great video.

That was SICK!! Doing an ambulance live-in/4x4 conversion. Need to do 12 different power runs and this gave me 90% of the info I needed. Many thanks. Awesome jams as well. Keep it up!

Well done good sir... Thank you!

Great video and Channel love the content

Looks Great!! Nice, simple, clean and room to grow!! Thanks for putting this video together!!

I have watched this several times over the years and this is one of the best videos for explaining a relay and how to install hats off brother

Song: "Unbreakable" by Jay Kill & The Hustle Standard

Might I suggest you using rivets for the mounting of the relays and power distribution blocks to eliminate the need for long screws sticking out on the back side, even plastic rivets if plan to be making changes. They are easy to cut, cheap to buy and look clean. Other than that, extremely nicely done.

Perfect, clean, direct and good music. Thanks my brother.

Coming from the guy that is known by family and like to have E-fans wired with used relays and speaker wire I must say, this is awesome and seeing that its actually that cheap and easy to build I intend to do a setup like this on my truck. Its getting some major racing style mods and changes so a good really relay setup and not the disaster I have no would be a good change of pace. Thank you for making this video. I don't know why I have not found you sooner but you are the boss!

Pretty good video, thanks for the information. However I must say there are a few soft spots in the provided information. 300A breaker won't help at all as the gauge wire you are using from the battery is too thin, the wire would melt before the breaker gets even close to pop. Another thing to note, that 10 way fuse block has a max of 30A per circuit and 150A per box, so again before the breaker pops you would blow the fuse box if you exceed the load of 150A.

if you use ground to trigger the relay you can have short coil power leads....plus you get the benefit of not running power wires through out the vehicle to switches,if they short it's just a ground not live power

Me and my friend are working on a project and missed our deadline and he got sucked into another project so now I have to finish it. I think this will be a good reference for wiring in the rest of what I have to do. Thanks for taking the time to film and upload.

Not sure if you are familiar with the SPod that’s used for Jeeps/off-road vehicles to simplify switch install when installing multiple accessories such as lights, but does this basically perform the same function as that in a DIY form? I much rather put in some work to make this and sage (lots) of money at the same time. Excellent video, 100% that looks extremely professional.

I have several issues with this. Firstly why such a high amperage circuit breaker? The supply wire to the fuse box will only take around 30A, so if the CB needs over 300A to pop the wire has already melted. The CB amperage should be no more than the maximum rated capacity of the wire. Next, the circuits attached to the fuse block should draw no more current than the main wire to the fuse box. Need to be careful here. And finally, my major bug bear here is the crimps. There is no need to solder and crimp. Crimps, when properly done with the correct tools and techniques offer similar electrical properties to solder joints. Crimps have much better tolerance to vibration and are less likely to fail in an automotive setting. Aircraft only use crimps for that reason. I also abhor the pre-insulated terminals. These are best kept for roadside repairs, not main electrical installations. Delphi, Tyco, AMP, Amphenol, Sumitomo, JST all make W crimp connectors which are far superior to the ones shown. Can you explain the logic behind heat shrinking a pre-insulated connector? It would save you more time if you used the W crimps and heat shrink, and give you a much better finish.

300amp breaker!! wow, good to see that you're power supply wire to the fuse panel is going to with stand 300amp. haha, more like 30amp. wouldnt be a bad idea to work out your actuall load before you just go fit a 300amp breaker and a bit of 6mm wire so it will actuall trip if there is a short and not just melt the wiring.

I just found your channel a few weeks ago. Some of us old race car guys that did it back in the day didn't have much access to the parts that is offered now. We had a gas and acetylene torch and maybe one of our friends had a arc welder to do what we needed done. As far as the electrical not much was out there for a 12 v system. A Ford starter solenoid was used for lots of things...Glad to see you DIY and other video's....

I just came across this video and OMG it clarified my questions about how relays can play into my car audio builds. Thanks for putting this out there.

great video can u tell me the name of that song that was playing

Ben also said “Beer is proof that God loves us!”

This is the first video of yours I've ever watched and I came actually for a completely unrelated project, but your video gave me the answer I was looking for so I just wanted to thank you! :) Also, I admire how professionally you made that look, I'm very impressed and definitely subscribing.

I’ve watched 4 videos so far and this was the most simplest video I’ve watched! Will rewatch until I put it in the car.

The music makes it sound like you are making somthing very important

aluminum plate would work instead of the plastic. may be easier for some to work with. Hammer and Street curb. lol. could also ground thru the aluminum.

Having done a number of these types of jobs, your technique is spot on. Also for a "Friday" video you should do a Weller PortaSol if you have one. I love mine.

Great video, nice , clean, easy, and basic wiring knowledge. Thanks for posting !

At 11:30 you mentioned things like this make you look like you know what you're doing... Everything except for the soldering part. Totally no needed with the proper crimp. Definetly wouldn't solder the ring terminals to the distribution block either.

music is slappin

Thanks you so much for this video man. I’ve been on forums for 3 days trying to teach myself

Just stumbled on this video and it’s exactly what I was looking for to wire up some lights on my Jeep. I can’t justify spending $700 on a sPOD when it’s basically the same thing as this. Thank you for the links. Just ordered everything I needed for under $50

those chinese breakers are garbage... a 300 amp breaker "MIGHT" work for a 150 amp load.. maybe.. and that's only until it trips once or twice.. then significantly less... they are a fire hazard.. we tried using them for car audio and it was a disaster... only decent high quality marine breakers will be adequate for a 12v system.. and they are expensive... better to use a good fuse instead.. or spring for the big bucks to get a decent breaker

300amp beaker for 50amp wire hmmmm 🙅🏻‍♂️

hey thanks for answering my other question, I have one more: With these setups, what do you do with all the black or negative wires coming from the accessories? Thanks.

Great video. Very well explained. I have a load of additional items going in my Land Rover and this video has been invaluable in explaining how this is done. Thank you.

One of the best done videos seen on Utube, irregardless of subject matter Proven by comments. Well well done young man!!

I love the way that looks !!! That plastic mount was kinda hard to tell by the video but if its textured (grained) on one side and smooth on the other I think its referred to as Kydex. It can be bought in different thickness's and in full 4x8 or 4x10 sheets. it comes in black or white. we use it a lot for heat/vacuum forming parts .Love the way that assembly turned out.

DUDE! Thank you for posting this. I learned a ton and am currently right in the middle of my own build.

This is the most educational video on KZfaq well explained 💯💯💯 been watching so much videos and no one explained it this good!!

Made mine with help from this tutorial. Over a year now and still works great! Thanks.

thanks for helping me with my fuse block! side note - thanks for the song. i had to look it up, and i'm glad i did. i struggle with PTSD on a daily, and that song helped me make today a good day. i must have listened to it a hundred times by now. so. thank you twice.

for someone who is obviously not a 12 volt specialist I am very impressed with the look of your build. as a 12 volt guy I give you props on your work my man

Dude, this channel is now my fav channel... Fabs like I do, cost effective and clean! Well done!

Dude I give you Props, You made it look so EASY and well explained....Thanks

Seeing your design sparked a light bulb.I've been trying to find a way to wire stuff on my resto project. Now to make it work in a engine bay. You're a genius

Mounting board looks like Sintra. Really easy to use thermoplastic and can be molded with a heat gun. Used to work with that stuff all the time. Great Video!

You are an artist...that looks really neat

That looks killer. So clean and professional looking. The music you chose is so good.

That looks very sharp and organized. That 10 way fuse block is just what I need to clean up the wiring on the 80 Powerwagon. I have added over a half dozen relays over the years, for the heater fan, offroad lights, high beam headlights, ect... It's all zip tied or taped up under the dash. Hell I look up under the dash and I don't know what each relay powers. Really enjoyed this video, now I know how to clean up that mess.

This guy is 'money' and I sure appreciate the help he provides. I like doing my work extremely clean and following the lead of a true craftsman is the way to do it. Thanks so much, bro...great show

That is definitely a super-clean board with excellent wiring. It just takes time and patience when working on something clean like this. Over my many years of working on cars (amateur of course) that taking your time and thinking through what you are doing is the absolute best approach When I was a teenager, my wiring was bird's-nest all the way. All these years later I have learned good ways to wire things and be neat about it. Not up to par as what is in this video. But my workload has never been this large, either. Good Work. Thanks for the video and the information with it.

Thank you SO much for this video. This really explains alot and simplified things. Quick question. So you have a hot and ground coming off of both your switches and your device (fan, lights, etc). In with this set up, the hot comes from the switch into this fuse block, then comes out to the hot of the device. Where do you run the grounds to? (of the switches and the devices). Just ground them to the frame close by or something? Thanks!

Now that’s a piece of art! Beautiful wiring job. Great video!

thanks for the video, i wanted to ask as a switch also needs power would this connect to the other side of the fuse block? so in effect a horn for example would need two fuses one to the relay and one to the switch.

Great video brother greatness!!!! I watched this video years ago and have done so much work thanks to your teaching!

I've been looking all over for a good diy video and I've finally found it. Been wanted to add 4 separate light accessories but didn't want to keep running wire to the battery for each one

Thank you, I had bought the stuff when you posted the video finally got around to assembly and I'll admit i watched it about two more times for reference.

always looking quality! ! love the channel! !

So clean and simple.. amazing!

Great video, thank you for posting I'm definitely following this! A couple questions though. What type of switches do you prefer using? And my swap will need headlights, tail lights, turning signals, fan, fuel pump, and ignition, will this type of setup work for all those mentioned?

Ah man still one the best videos out there man! Thanks!

This is one of the best explained and shown videos I've seen so far.. and back ground music was a good choice.. for me it kept the tutorial calm and relaxing.. Thanks for the awesome video

Just ordered all this stuff. Gonna be building a costom fuse box for my 94 trans am formula.

Awesome video! Watched three time just to hear the music. I've have to tackle the wiring harness in my camaro build very soon and lots of anxiety. Your video has given me some direction. Again great job.

My favorite wiring video! Ive watched this so many times. Its just awesome!

I was skeptical, but I stayed for the whole video. Thank you sir!

I’m about finished with mine and mounting in my Jeep thanks for a great video!!!!!

Great video. Something that would clarify a question for me as I've ordered most of these components, received them, and am getting ready to replicate your project, is how possible would it be to translate which numbered pin on the relay (30, 85, 86, etc) goes with which color wire to each terminal? Like, the 30 pin on the relay -> blue wire -> + battery power. Any help is appreciated, keep up the excellent customizing.

Awesome video on this subject. I know a lot of people just Go Off trying to do something like this but, I think you made this video very helpful. Nice Work.

Nice work with the videos man. Learning alot through this. Nice music and music volume choice, great explaining and clean working. Thank you for this. This is the only channel ever which i turned on the bells for☝🏻☝🏻

I have to relay boxes in my engine bay, I'm looking to rerouting into the glove box. Close to the same process as this video?
