Great to hear!

That's awesome...I was hoping to get one person, 😆...thanks for watching Bdub!

Don't hook them together. Secure them to themselves. ***disclaimer....always consult with a qualified professional. Videos are for entertainment purposes only****

This was my problem, too. My adapter harness to my car doesn't have a dimmer wire but an illumination wire while the after-market radio is reversed. Thank you

@@generalsteam1120 my recommendation is to go ahead and not hook them up together and just wrap them up separate and not Oakland together at all. This is the exact scenario that I made the video for because a lot of the time, if you hook those together, you created short. The radio will still work as intended except you might not have the dimmer come on when you switch on your headlights. But as a disclaimer, always check with a qualified professional, as I am just some guy on the internet:-)

Same question absolutely Noone has an answer to it anywhere I've been looking for literally a week 😂

Hey Rob, I would try disconnecting the Illumination wire also (they are sometimes not needed in install either)...and if that does not help, go back over your connections to make dang sure they are connected and are not grounding out on anything do to exposure. I believe that would be a good place to start. Hope that helps. I know wiring issues can make you want to break something...just don't let it be your stereo;-)

Hey D.j. B, let me ask around and see what I can come up with too. Sorry to hear about your trouble by the way:-(

Yes brian031.. it is not necessary to hook any of those up.. the radio will still work, just might not dim with the lights when turned on:-)

Ok, what I'm going to guess is that the wire that you mated with head unit wire was actually dimmer wire and head unit wire was illum...check fuse, replace, and then leave those unhooked but capped so they don't short on something...let me know how it goes!

If no illumination wire is present on factory harness, then no need to hook up wire...you can still manually dim most radio screens:-)

Hey BillyzTube...sorry to get back with you so late! definitely sounds like there are a couple of wires connected to wires that are not supposed to be mated together. That is the problem with doing your own splicing together and not using an aftermarket harness (unless you do this kind of job a lot). My guess is to pull head unit out again, go back to research drawing board (Internet), and try and find your factory wiring schematic again, and try seeing if there is something that you are missing as far a s what wire goes to what. Hope that helps, and hopefully by now you got the problem fixed. Let me know how it went;-)

If the aftermarket wire harness has a wire that is specifically for illum. (but not the orange color cause sometimes they are different), then hook up the illum to the illum on the factory harness, and then tape off the dimmer (or cap it off...just don't use). If there is none for the aftermarket, then tape off both the illum. and dimmer separately on the factory, and do not use...they are not necessarily needed. Let me know how it goes Ja Chavez, and THANK YOU FOR watching and comment.

Hey Jorge...thanks for comment:-)...Yes, on this head unit, I left dimmer out because it is not needed. The radio has an option to manually go brighter or dimmer if you want. And, it also automatically gets a signal to dim when you turn on your headlights (just does not respond to signal from vehicles dimmer dile knob). And, not to familiar with iphone because I've always had an android device...but this unit has an option to connect via your Iphone, but is not specifically set up to use carplay and I would purchase this one if you want to take full advantage of what your phone and a true apple carplay head unit would allow. My next video is going to go over most of the features I can use on...but I have an Android (LG stylo 4). Hope this helps:-)

Oh, and if you know what wire is the actual dimmer wire from factory harness...you can absolutely hook that up to dimmer wire from head unit (as well as the illumination wire from factory or aftermarket harness to head unit harness, but spliced altogether on same circuit)...just make sure you know that is dimmer wire from factory harness for certain!

Let me know how it goes, and send me a pic of how it went if you'd like:-)

Shoot Melissa, I'm sorry that is happening to you...I know how frustrating that can be! My first step is to always try the obvious things first (which it sounds like you did, but just double check), and make sure each wire is going to its correct mating wire. Then find out what fuse #6 goes to exactly to give you an estimate of what is "tripping". Normally, those Key 1 and 2 wires are for your steering wheel controls, and there is usually a Key-GRND also that needs to be mated to ground wire if using key 1 or 2 to prevent fuse "blowing". Otherwise, you might need a converter like an ASWC1 to convert signal. Those are some of the things I can think of off the top of my head. Let me know how it goes!

Yeah koolNkuiet...as long as they are both for illumination, then you are all good. Some harnesses put that color in there for some reason...I guess to try and trip us up, lol. (But as a disclaimer, always have a qualified tech check your work out to insure correctness and quality.)

Any question is a GOOD question:-) Technically, you do not need to hook up the illumination wire for lights to work on some units, but to answer your question directly...my understanding is that it is POSITIVE and it is a variable power because the dimmer switch on your dash is variable. As always...comfirm with a qualified technician as *my advice is for entertainment purposes only*

Hey Tyson...sorry I did not get back with ya. What kind of aftermarket harness do you have, and what is make of vehicle? When in doubt...you don't technically need to hook up any of them, but give me that info first.

Hey Aryan...that's exactly why I made the video, because I've been in your shoes. If your aftermarket stereo wire is marked "dimmer", then hook up dimmer to dimmer wire on harness. But most likely, it is marked illumination, and it should be mated to the illumination wire...then the dimmer extra wire gets capped separately and not hooked up. But as a disclaimer ***make sure you consult a qualified technician about this***

@@hurstysgarage after doing that my dash gave the the check engine light and the srs light and my dash still wouldn’t light up

Hey Rene...It should not hurt to connect your illum wire to the dimmer on harness if those are only options...what year, make of vehicle and model and ill see what I can find out

Sounds like the wiring from stereo to factory harness (or aftermarket) aren't correct (or need to be checked)...so I would start there (download wire locations from internet). Let me know how it goes Rob, and good luck!!!

Absolutely, glad it helped:-)

I agree totally 6pgregma...the only thing that saves me from being "totally blind" at night is the feature when you slide down on top of screen that says notify and setting...you can turn screen to "off", and radio or music still plays, but screen goes pitch black. Hope that helps.

This guy either shows all three wires being connected that is wrong or else connecting the illumination wire from the radio to illumination wire of a car when I say why does he not show connecting the illumination wire from the radio to the dimmer switch of the instrument panel if the illumination were that comes from the radio lights the display then two wires should be connected one wire coming from the stereo needs to go to the dimmer wire not the dimmer wire with the illumination wire coming from the vehicle harness the illumination wire from the car stereo should go to one wire the dimmer wire not illumination to illumination if you want to dim the display with the instrument panel then you must use the dimmer wire to the illumination wire coming from the stereo not the illumination we're coming from the vehicle harness

Absolutely poli 12 zansty...hopefully it helped you out...did you get your install done?

Ok Bdub, I would try 2 things first...make sure connections are all connected to the right wires, then make sure none are touching (simple things first). If that doesn't help, then try hooking up stereo to a vehicle that you know the existing stereo works, if it is that important for you to use that one, because it sounds like the faceplate/unit is bad, especially if there is no sound. I have a video on how to hook the stereo up to a home conversion to be able to plug it in to an outlet so you could check it that way to be sure.

Here is that video link kzfaq.info/get/bejne/nMmah7lynJ3KlY0.html

Let me know if you got it working, but it just sounds like a bad unit.

@@hurstysgarage thanks for the response . When I get back out on boat I’ll double check everything. What sucks is I bought the unit over a year ago and just now finding time to swap it out. It has a 1 yr warranty. Go figure. I was thinking it was a bad face plate as well.

Hey Martin...you will have to use some type of 12v power circuit supply detector (make sure it is grounded before using as to not blow a fuse), so you can see what wire is "active" when vehicle is on. If you are trying to find the wire on the actual head unit itself...I suggest you try and find a website on the Internet that has a wiring guide specific for your year Toyota, and the model of the head unit. Sometimes you can free access to Chilton Manuels that have those schematics, online from your local Library. Good place to start anyways. THANKS FOR WATCHING, and let me know how it goes please:-)

Absolutely Sal...just as long as they are individually wrapped or covered (so they don't short anything out):-)

Hey Marcos...I would not! Connecting them both together usually creates problems (i.e. like shorts, blown fuses).

@@hurstysgarage thank you so much

Steve, some radios aren't designed to be compatible with factory harness wire to do that. If you hook illum to dimmer wire, a lot of times radio won't work correctly. Some don't need to have wires connected at all because they have a baclight adjuster for that. You can try, I just don't want to see you blow a fuse or worse...but if you are confident in your wiring skills and no your head unit and vehicle harness well, then by all means, give her a go...I just show you how I was taught and from some experience (I'm not a guru though 😉) Let me know how it goes though ok:-)

Hey Angels...it is short for KEY 1 and KEY 2 which will be used to interface steering wheel controls if your vehicle came equipped. Although, some vehicles will need the ASWC-1 module still to translate the steering wheel controls to the stereo. Thanks for comment;-)

GND Key1, Key2 Basically, the head unit produces 5V from Key 1 or 2 then when grounding it makes the loop so that when you press a button on your steering wheel, then the head unit detects the appropriate voltage drop and reacts to that. Long story short...for steering wheel controls:-)

You were the first...whoo hoo...Alyssa's world rocks! Everyone, check out her site:-)

Thanks sweets:-)
