70 RR MAP Light (A01) bulb question.

[70RRGuy]

Need some help with the bulb for the MAP light. There is a pink and yellow wire to the MAP light. I think the pink wire is the curtesy wire that allows the light to come on when the doors opens. Then the yellow wire is used through the switch to turn on the MAP light when the doors are shut and engine running. Is the pink wire a 12VDC supply or a GND? I'm going by memory but I thought the pink wire was a 12VDC supply. The yellow wire is a 12VDC supply as well. If both the pink and yellow wires are 12VDC supplies then the GND must be through the case via the dash chassis.

Here's the question about the bulb, is this suppose to be a double filament bulb with the outside case as the GND? The bulb I have is the #90 bulb but it is a single filament. It has 2 terminals on the end of the bulb where one is 12VDC and the other is a GND.

If it is supposed to be a double bulb, then can someone recommend a part number and a company to source one?

Nope.. Single filament, #90 bulb is correct..

Just my $0.02...

My owners manual says a 90 bulb.

Pink is 12 volt hot all the time. Yellow is the ground circuit and it is normally switched to a grounding style switch.
