Left blinker and brake light not working on trailer connector!?
On my trailer connector i have a 'line of fire' led strip and when i brake and use my left blinker it doesnt work. The strip isn't bad cuz i checked it on my friends truck. I cant figure out which wire goes to the left blinker/ brake before the yellow wire that goes into the trailer connector. Any help would be great, i use my truck everyday for towing boats and already have a 5-day tag for a bad light on my truck.
