Wiring

The room lamp has one side of the lamp (RL wire) always hot from the L wire of the fuse box (Fuse 'C'). The switch has three positions:

* Off
* Auto (center)
* On

Album 20758

In the auto position, the light is grounded by the Door Switch (BR wire in A-pillar). Usually only the driver's side door has a switch. In the ON position, it is grounded through the ground wire in the headliner (or with standard switch, via the attaching screws).
