RAM 2500 Van V8-360 5.9L Magnum (1995)
Backup Lamp: Description and Operation
In the RUN position, the ignition switch connects circuit A2 from fuse 2 in the Power Distribution Center (PDC) to circuit A22. Circuit A22 feeds a bus
bar in the fuse block that powers circuit F2O through fuse 6 in the fuse block.
Circuit F20 supplies power to the back-up lamp switch. The back-up lamp switch is part of an assembly that includes the Park/Neutral position switch.
When the operator puts the transmission in REVERSE, the back-up lamp switch connects circuit F20 to circuit L1. Circuit L1 feeds the back-up lamps.
If the vehicle is equipped with trailer tow, circuit L1 splices to the trailer tow harness.
