Harness for fog lights

Anyone had success with aftermarket fog light harness for OEM fogs? My SR didn’t come with Fogs, got OEM pair off from here, tried after market harness from eBay. Relay makes a clicking noise when turning off and on but light don’t come on, also switch back light is always on. Seller said try cutting the + and - wires leading to the fog lights and reverse them. Sounds dumb, still going to try it tho. Anyone had success with any particular harness that can share ?

 

Sorry you are having trouble Woocawachie, you might want to contact the guys in Georgia @ headlight revolutions! They are very knowledgeable on lights like that and test everything . Have you tried a load resistor for the switchbacks. I use to have a 2004 sierra sle and changed everything over to led's and on the turn signals had to solder and mount resistors to get them to work because the led's light emiting diodes current runs one way and burn almost no powerseen by the electrical controllers on vechicles. hope that helps my friend ! Have an awesome week smiley tn1

 

Thanks for the info. Will look into both.

 

I was able to get the fog lights to work. However, I need to tap into existing wire somewhere so the switch “back light LED” can turn off and on based on when the headlights are on. Currently, the back light LED on the fog light switch is always on. Does anyone have an experience to where to tap this wire into?
