I'd be suspicious that there was a ground problem or a wiring problem. A
ground problem might return the backup light current through the brakes.
A wiring problem might have brakes and backup lights shorted together.
Shouldn't be hard to find. The problem has to involve the backup light
circuit from the truck, that's all that changes from forward to back.
First thing to check is to see of the backup lights light with the brake
application in the truck. Its easy to confuse the pins inside and out
and make such an odd circuit.
