Hey guys I just recently installed a new third brake like and i was so excited cause it was finally an easy install. I was very wrong. I plugged everything in and all my lights went on besides my L.E.D.'s. I know it is not the actual light because i plugged the harness for the L.E.D.'s into one of the other lights that were working and they lit right up. So i have narrowed it down to the wiring of my brake light. Does anyone know a way of finding out where the problem lies exactly in the wiring? does that part of the light run off it's own fuse?

 

Was the factory CHMSL working when you took it out ?
