Reverse is working fine. I just got this car last fall and the previous owner didn't even have it hooked up. I think he was having a hard time finding the reverse light housings because they covered them over before painting the car. He gave me a set of the lights with the car, so apparently he did eventually find them, but the holes need to be opened back up and tie them back into the wiring.
Sounds like I would be better off to pull the one I have out to see which one it is before ordering if there are two different options. I wonder what determines which length is needed? Year of the transmission?
