At the drivers side junction block on lower left of dash, check Gauge fuse 10amp.
The black and yellow wire should have power at all times as long the 10amp fuse is good at the transmission back-up switch
Also at the red and yellow at the back up light switch at transmission should have power when key is in On and gear shift is at reverse.
No power at red/yel and power black/yellow the the switch is bad.
No power at black/yellow track it back to the ignition switch thru the 10amp fuse
