4yr old video and still helping people. Great job eh. A giant thank ya from the U.P.

HANDS DOWN , the easiest most comprehensive explanation/tutorial I have ever seen regarding Trailer Lights on KZfaq. And a fantastic 101 for how a basic "circuit" works. Well done sir!

Bless your heart!! The best 20 minutes I could have spent to get a basic understanding of short vs open circuits! You are a fabulous teacher.

So here’s the deal …. I know you did this video five years ago but I just viewed it because I am having some trailer wiring issues. Your video helped me to understand that I personally have had an “open circuit / burnt bulb” for 69 years. It has originated in my brain. Lol. THANK YOU SO MUCH FOR YOUR LAYMAN EXPLANATION OF TRAILER WIRING. IT IS GREATLY APPRECIATED.

The second video of yours I have watched as I try to trouble shoot my trailer lights. Amazing videos, very clearly explained and understandable. Thank you

Awesome video! Thank you for making this so easy to understand, even for someone who has no background whatsoever with this!

Thanks you thank you thank you!!!! I have had an issue for a long time...rewired my whole trailer, lights didn’t work, popped fuses, etc. I watched so many other videos without success. Watched 3 of theses series and finally fixed!!! Your simple explanation of how the trailer becomes the white wire did it!

Great video! Taking the time to explain the flow, or lack there of, for electricity and how both the truck and the trailer frames play a vital role was perfect. Thanks for going into such detail, now it’s time to apply the new knowledge! 🙏🏻

A absolute must! Trailer wiring 101! This is video has an excellent drawing with clear teaching of the trailer light circuitry.

Thank you!! I was planning on taking a couple of calves to the sale barn next week so decided to check out my livestock trailer today. It'd been working perfectly, but today I found no lights at all, so I did the obligatory walk around looking for broken wires or any other clues. Even connected the pickup to another trailer to make sure the problem wasn't with the truck. The other trailer worked fine so it wasn't the pickup. I then decided to get some guidance from KZfaq and kind of randomly picked this one. Glad I did. The infamous "white wire" you mentioned being the ground running from the plug (mine is a 7 point, but grounds the same) appeared to be connected to the trailer (but with a pop rivet, no less!?!?) and the wire was unbroken. The pop riveted connection, which was to the underside of the trailer, did look a little flaky. I cut the factory white ground wire and using a crush connector, I attached a piece of solid copper wire to the end of the braided copper trailer ground wire, drilled a guide hole in the frame, then using a self-tapping metal screw, attached the solid copper wire. Immediately, problem solved, saving hours of time not to mention the frustration! Thanks again!

Great overview making everything simple to understand. You have a gift for teaching!

Great presentation that clarifies basic concepts

you're a great teacher. Very clearly explained for someone (me) who is a newbie! Thanks

Best description of a trailer circuit I've seen. Tank you!

Retired high school electronics teacher here.... nice job with your visuals, video inserts, and explanations!

Unbelievably helpful! Thank you for the in-depth break down!

Thank you for this. Getting ready to rewire my old vintage trailer camper and didn’t have a clue how to do it. You are a good teacher.

I really appreciate you for taking the time to make this video and providing such a thorough explanation.

Thanks for a very informative video. I had a u built trailer that had some challenging wiring that needed to be troubleshooted. With the knowledge gained in your video I was able to fix my trailer lights myself. Thanks for going full geek and showing the wiring diagrams on a whiteboard!

Thank you. You know your wiring and how to explain it simply. Great video.

Great tutorial mate. I really enjoyed it. Thanks Mate

I've watched tow of you video's so far, both on trailer lights and issues and you really helped me...Thank you

Great presentation,best one I've seen on this subject.

Wonderful and insightful overview... Thank you!

You are an awesome teacher! fantastic video! Well done Sir.

Greetings from the Adirondack mountains of upstate NY. Really enjoy watching your hunting/fishing vid's, please keep them coming. (would love to see a tour and/or hear the story of your camp sometime) Also nice to see someone sharing practical info in a world where so many people can't be bothered to fix simple things and many dude's don't even know how to change a tire!!

You are a very good teacher! Thanks for sharing your knowledge!

Excellent Instructor. Thanks Dave. You help me clearance lights on a mini Bus. The principles still apply.

Excellent work on explaining. Thanks

Excellent video. Well explained. Thank you!

Very Well Presented! Thank You Captain Carpman

awesome practical advice - thanks. It made it all much simpler to understand

This series is fantastic! You are a wonderful teacher, all concepts are presented in an easy to understand format. I just built my kayak trailer and something went wrong with the wiring. I am a novice and a wildly independent woman, determined to complete my build. Now with all this knowledge, I can easily address and fix! Thank you and God Bless!

Amazing video and great explanation on how the trailer lights work! Thank you so much!

Bloody brilliantly explained. Well done.

Thanks Dave! After trying all of your recommendations, I should’ve started with the easiest one first. Just because my truck is a 2021, does not mean that the trailer parking lamp fuse is not blown! I’ve never had a trailer hooked up since I bought the truck, but low and behold, that fuse was causing my running lights not to work on the trailer. Brake and turn signals worked, just not the running lights. On the bright side now I have a wire wheel and a multimeter for my tool shed.

Thanks, this was fantastic and very helpful.

Excellent presentation...thanks for the step by step👍

OMG, thank you!!!!!! You are truly the wiring/circuit whisperer.

Excellent instruction. Thank you

Excellent Video! Never really understood trailer wiring until now. Thank You.

You made it so simple, that I got it in one shot, thanks a lot pale, you are the best!

Great video, easy to understand. I wish you were my neighbor. Thanks. Wish me luck getting my rear submersible lights working on my trailer. 👍

Awesome video thanks

Just bought a used boat w trailer. Lights didn't work. This video gave me lots of info to troubleshoot the problem. FIXED! Thanks.

Perfect. Great explanation. Many thanks. 🇦🇺👍🍺

Another good one!

Excellent job

Very good video easy to understand thanks

Great video! I spent the afternoon troubleshooting my trailer lights. Almost every problem I've had in the past have been due to grounding problems. I couldn't understand why my brake lights and turn signals worked perfectly, but I had no running lights and no side marker lights. After checking everything I could think of, I found that if I moved the swing arm of the trailer I got the lights to flicker on and off. It appears that corrosion was the problem and cleaning the area around where the pin secures the arm was the fix. Also one thing that I do before backing the trailer into the water is to disconnect the wiring harness in order to not blow the fuse in the truck.

The best explanation ever! Thank you Bro….

Finally I come across someone who explains it just right.. Thank You.

You just saved me a headache brother! Thanks for the explanation of trailering and short vs open circuits. Thank you!!!

Really good explanation really nice

Great information thanks

I have to say you are very very good I appreciate the way you explained it and very simple way I totally agree with you you are really good

Wow just what I needed thank you sir

top notch video TY

Best video. Helped me understand

Thanks. I’m going out to look at my trailer wiring now!

fantastic, now I understand. thanks!

Great video indeed !

That was awesome 😊 thank you

great video thanks man, easy to understand for dummies like me hahah, appreciate these videos man!

Man, you have a knack for teaching. I learned a lot.

Very informative

thanks for the information! i have running lights that won’t work on a trailer, even though the brake and signal lights do work. i should have a short circuit, i’ll check if i have any blown fuses to confirm!

Your channel kicks ass dude hahaha

Thank you, man. This is very helpful to me as I troubleshoot my faulty trailer lights this winter. Also, your "TRAILER" has no wheels 😜

I've been searching for a good explanation to my potential trailer light problem. This was awesome!! I pretty sure I just have an "open" circuit. I just need to find it now. Unfortunately, it's not my bulb. :(

Great video, thanks for taking your time to explain all. I have an issue after new LED light installed. only when turn on the right turn signal, all trailer lights blinks (other side turn signal and brake light blinks). But if I turn on the left turn signal, works perfect. Thanks again.

I have a trailer with LED lights on the back that I installed for extra lighting when we are at events. The trailer has it's own battery that the lights are hooked up to with switch. I want to be able to use those lights when I put truck into reverse and they come on. I have a diode but not sure how to wire it up. Any help would be great, thank you.
