LED DRL wiring help

5295 Views 23 Replies 3 Participants Last post by  Devin0305
Hey all! I have posted about this in the past, and got a good answer... for part of my project. I got these XKGLOW drl switchback led strips to put into the retrofit headlights I am making myself. Now, although I have done some wiring in my car before, I’m still not incredibly skilled in it, and need some help with where the wires should go and the best way to go about it. Below should be a diagram of the wires. I want to hook the white drl wire up to the fuse that goes to the radio, so when the car is powered on the strip comes on. As for the other 3 wires (red, black, and yellow) I’m not exactly sure on where to connect those wires. I was thinking of bolting down the negative to a bolt somewhere in the engine bay, and the red to the positive on the battery, and the yellow to one of the wires in the wiring harness for the turn signals, just not sure which wire. Any suggestions or help would be greatly appreciated, especially since I’m not sure the best way to go with this. Thank you!

The turn signal/marker lights have 2 wires. Get a voltmeter to see which one you have to tap into (12v+). Black is normally ground, but still, test it!
Thank you for looking at this! I really appreciate it! But what about the red 12v positive? Should I just hook that right up to the battery?
I don't know, I would have to see how your kit works. My LED (vLeds) are plug-n-play as are my retros and fog lights (Morimoto LED). I didn't have to tap into anything. I would think the 12v+ go to your "parking" lights, again, I don't know how you are supposed to hook this up to your rig. Post your instructions, maybe I and someone else can chime in and help ya out.
https://images.carid.com/xkglow/pdf/xk043001-mounting-instructions.pdf that’s a link for the instructions that came with the led strips. I now know (thanks to you) where all the wires should go except for the red 12v positive. Assuming it just needs a 12v source to connect to in order to give it power, so the white drl positive wire can connect to the radio fuse, black to ground, and the yellow to the 12v positive within the turn signal harness. Also another question, would you suggest just using a t tap in order to connect the yellow wire to the turn signal wire?
Sorry, been crazy busy. So then, the red 12v+ should go to a switched (circuit is on when you turn the key and turn the electrical system on.... just before you turn the engine on) wire. DON'T hook it up directly to your battery. I'm still confused on the (white) DRL wire. My guess is that is acts as a signal to dim the DRL kit????? Anyway, that is my best guess.
Ah yes. That makes much more sense, I’m getting the red and white mixed up. Honestly, I’m not sure either what it’s for or where it would go. My guess is it’s for newer cars so the white would hook up to those drl’s. Hopefully I won’t have to use it and forget about it, but we will see when I’m able to test these out. Appreciate the help, will post pictures and update the thread about it :)

Edit: the red and white must be connected to the same power source. They go together to turn the drl’s on.

Alright so one more thing, one more question. So, I want to hook up that red wire to a switched wire in order for the drl to come on when I turn the car on. Is the best course of action to run the red wire to the interior fuse box under the drivers side, and tap in to the ACC radio fuse? Or is there any open fuses that might work as well?
I do apologize for all the questions, this project is racking my brain, and I just want to have good looking headlights that work right.
So under the hood there is nothing you SHOULD tap into being they are major functions of your car. However, inside, under the dash, there is a fuse for the radio. Before you go tapping into this, what are the volt/amp requirements of the DRLs? They should not exceed what the OEM (factory) can handle. If they are lower (we know it requires 12v, but how many amps does it need? I'm thinking not alot ............), when tapping, use an Add-a-Fuse product (safest way... use Youtube on how to use/install one safely). Hope this helps,

Here is a link on the car's wiring/fuses:
This does help a lot and thank you! I would assume the Amps is 10 (being the headlights are 10, and other videos of installing drl led strips in cars say 10amp fuse) but you’re right it doesn’t say. Those videos have different leds and different cars, so the problem still sticks. There is the accessory fuse, but that is 15 amps. Installation tutorials on fog light kits for the 2008 say that the fog lights install to a 7.5 amp fuse where the drls are. I’ll have to try and find more information on the strips. Again thank you!

edit: the wires themselves on the strips don’t show, they are protected. so it’s hard to find exactly what the gauge is for the wire.
18-20 gauge will work fine.
Thanks for all your help, truly. I would hope that the accessory fuse would work, but that’s 15 amps, so the ACC and radio fuse should work the best. You’ve really helped me figure this out and a million thanks.
so ive got LED DRL's that are just plain positive and negative, if i tap them into the turn signal wires would they blink with the turn signal or is that what the third wire is for?
Red goes to your switched wire. Black to ground (a bolt in your engine bay would work fine, or you can connect it to ground in your turn signal wire) and yellow goes to the wire for your turn signal that turns off and on when the signal is used.
i figured it out. none of my headlight wires had constant power so i tapped the oil level sensor fuse in the engine comp fuse box and so it runs power any time the keys turned. we all good
Does that run into any problems?
as far as i know, no. seen posts of other ppl doing it and its ACC so it works well, turns off with a relay click abt 20 seconds after key turns off. worked great all day. To anyone reading this if you do this i did a 10A and 7.5A fuse for the lights and oil level sensor for the fuse tap.
I’ll have to try it out. Certainly seems easier than running wires to the fuse box under the dash
oh yeah much much easier. i can draw up a crude diagram to follow if you want
That would be great!!
put way too much effort into this lol but i tried my best, if u have questions lmk
