Door Sensors
Instead of buying a 2-wire room lamp, the 1-wire type can be modified so that the lamp lights when a door is opened. There is no OFF position, but the lamp will go out when the door is closed.

Isuzu Alternative
Reportedly, the 2000 Rodeo sport the same or similar Room Lamp to the late 1200 (both with door light positions)
Astro_Boy: was looking at a 2000 model rodeo ute that was crashed and would you believe it? THE INTERIOR LIGHT is the same size and shape as the standard datsun one, but with a door sensor setting!

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
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).
Dash harness has the door switch/room lamp wiring
Black Ground Black/red Ground from door switch Red/blue Always Hot
- 12V is supplied by 'C' fuse in Fuse Box (C: Cigarette, Room, Radio)
- Ground wire out of Lamp may be a short wire that bolts to the roof metal
- Early truck lamps have no Ground wire (black wire) but ground through the lamp screws. This is for use without a door switch
- 1973 used a relay, but with the same wire colors. The 1973 door switch is a double-switch (with an extra wire)
