okay, i just need to identify which wires are the 12v and ground for the door lights on a 2k. i see the bundle of wires that go into the car from the door, but if i look underneath the dash, there's a whole mess of wires and i can't tell what's what. is there a specific location/color that i should be looking for? thanks

 

buy a test light and probe different wires carefully! when you probe a wire hit the door pin in/out to see if the light pulses. and then pick any ground and your done. BTW dont forget to tape up each wire just incase.
