One question would be if tail lights are on.
Backup lamp power is usually sourced one of two ways. First is off one of the aux fuses at the end of headlight switch. Downside to that is backup lamp is always active and if you want to park the car and leave it in reverse the light is on. The other is being powered off the rear terminal on instrument lamp switch where the tail lights are powered -- or if accessible the tail light terminal on headlight sw.. There can be an inline fuse between headlight switch and that instrument switch terminal or there can be a fuse on the instrument lamp switch feeding the terminal. Downside on that source is headlights/tail lights need to be on to have backup lamp. With the back up lamp also being a dealer accessory there could be other power sources depending on how a dealer wanted to connect.
