    I switched bulbs and they still don’t work. Tail lights work tho. Is there a separate fuse for them? Help.

    Is there a switch in the shifter for reverse? Not sure how they are triggered, but if that trigger isnt being closed, that could cause it.

    The reverse sensor is in the tranny. Then the signal goes to the ecu and from there the lights. There is a sensor for every gear but the ecu handles the current via something. Prob a relay. You need to have fun with a dmm and work your way back from the bulb. Do you have a back up camera installed?

    The connector for the reverse light switch is right next to the connector for the neutral switch. All of which is right next to your shift cables on top of the transmission. This is what my neutral switch connector looked like.

    That could just as easily have happened to the reverse switch connector. It's super easy to check once you pull your battery. The reverse light switch is the gray one, shown at the top of my picture.
