I just installed led's in my bumper from custom classic. I didn't get the wire adaptor thing that you usually get with the led's from them. It basically is two wires connected at one end and one wire has a resistor on it. I wired them up and i can get everything to work except for the running lights. I also bought the one of those trailor light adaptors and i could not get that to work. If anyone has any suggestions that would be great.
