Backup Lamp: Description and Operation

On manual transmission vehicles the back-up lamps are controlled by the back-up lamp switch on the transmission. Power for the switch is supplied on circuit F20. This circuit is protected by a 15 Amp fuse located in cavity 4 of the junction block. The switch is normally OPEN.

When the operator places the vehicle in REVERSE the switch closes and power is passed to the L1 circuit. The L1 circuit connects between the switch and the back-up lamps.

Ground for the back-up lamps is provided on circuit Z1. This circuit terminates at the deck lid ground.
