Hey guys sorry to revive an older thread, but I’m having an issue with the exact SAME tail light set. I got them a couple weeks ago and my set has the exact same resistor that the OP bought off amazon, already wired into the brake light wires. Yet I still have NO cruise control. The lights in my housings all function exactly as they should, and I double checked all the fuses pertaining to the stop lamps and all my fuses are good. What am I missing? I can’t figure out why I have no cruise because the tails already have load resistors. Do I need the flasher relay mentioned at the beginning of the thread? Here are a couple shots of the tail light housings for reference.
The load resistors are wired into the middle light socket which I’m assuming is the brake lights and the top is turn signal? Is that correct? Or is it the other way around? I should add that the way there plugged in right now brake, turn, and the U bar LED, which lights up at night as the running light, function correctly.
