Hi everyone. New to the gbody world, just acquired a lq4 swapped 83 Grand Prix. I just replaced the headlights with a h4 conversion kit from Mikes Montes website. Comes with harness and everything. Question is for some reason the left turn signal quits working when I have the harness plugged in to the passenger side 3 prong plug. With the other led lights that came with the car plugged in it works fine. Has anyone had this happen with aftermarket headlight harnesses? Tried searching the forum and couldn’t find much on it
