I just put in a new Tail light converter in my SUV tonight, 3 to 2 and when I plugged in the trailerlights, everything worked except I had no stop lights and no RT turn signal. Running lights work except for one marker light. I have power through the converter and everything works correctly to the plug on the SUV side. Just curious where the issue could be. Dont the rear lights just have one bulb for the 3 functions? If not could it be an issue with wiring at the light? Just curious where to start.
