I have ddm tuning hid fog lights run off a switched relay harness since I don't have any oem wiring for fogs. The problem is that 9/10 times I turn em on only one fires up. I'm guessing the problem is the harness, it was one of the $10 ebay pieces of ****.
My question is, does anybody know where I can get a good quality switched relay harness? Can anybody custom make one? I'm don't even use my fogs anymore simply because one is always out and I'm ready to take care of it

 

Bump

 

you sure its not the bulb or ballast? did you get a chance to look at the relay? sometimes they can get fried. but i been running a cheap ebay one for years, no problems really

 

I got my harness from theretrofitsource. I also attached a switch and relay to my ground wire, so when my car turns on the fogs turn on and when the car turns off the fogs turn off.

 

There isnt much to a harness to make it not work. Relay is the biggest part they cheap out on, toss a good one in. If the issue isnt gone the ballast is the culprit.
