2012 LED DRLs
#16
Finding the 12 volt source is easy, what I'm asking is if anyone knows how to wire the actual LED light wires to the 12v. There are 4 wires coming out of the resistor box for the LEDs. The wires are as follows: red, black, yellow and white. I've tried using just the red and black but that doesn't light them up. At one point I had the white and yellow wired to the DRL and the LEDs worked. I have since reworked the headlights and needed to turn off the DRL so I need to find a way to rewire the LEDs to work independently of the DRL.

I purchased some new DRL inserts and have the wiring diagram below. I cannot figure out how to wire them to come on independent of the headlights. I wired them red to positive, black to negative/ground but they do not light up. There is a white wire that supposed to go to the headlight but I want them to work without using the headlight wires. Does anyone have an idea of how to wire these to be on when the engine is on without using the low beam headlight wire?

Maybe you need to plug them into the DRL/high-beam harness from the car. They are more towards the midline of the car than the low-beam bulb. I guess your kit would replace the 9005 DRL bulb (which also functions as high beam, so you'd lose that function)

From what I see it looks like the white goes to the headlight switch so when you turn on the headlights the white wire gets +12V from the switch. If that's the case then all you need to do is hook the white wire to a +12V fuse that goes hot when you start the car.

I tried to hook the red to the + on the battery and the white to an Accessory fuse and that did not work. I'd like to hook it up so that when the car turns on those lights come on without the daytime running lights being involved in the circuit at all.

DRL voltage?
I was finally able to get the led inserts to light but they go into shutdown after a few minutes. I believe the will only work with the white wire connected to a low voltage source (i.e. DRL). I had hooked them up using red to positive 12v, black to ground, and white to 12v switched (lighter fuse). It worked but after about 3 to 5 minutes they shut down. Does anyone know what the low voltage is for the DRL? I can try a resistor to duplicate it.

Finally got them working
As I have posted in past threads I was having a hard time getting the DRL inserts (added LED lights next to the fog lights) to work independent of the DRL headlights. I found the issue was that the controller that was included with the lights was looking for a low voltage signal from the DRL lights. I removed the controller from the equation and hooked the lights directly to ground and positive (wire routed from the lighter fuse) and they now work independent of the DRL lights. I also hooked up a rocker switch under the dash so I can easily turn off all of the new LED DRL lights that I have added (4 halos, 2 LED strip and 2 LED inserts). It was so easy that I neglected to think of bypassing the controller, lesson learned.
