My dome light, map light, vanity mirror lights, and glovebox light in my '90 GT don't work, nor do the lighted portions of the headlight/foglight and defroster/hazard switches. The map light did work for a few days when I first bought the car but then stopped working suddenly. I've checked all the bubs and fuses and they're fine. All the instrument lighting works just fine.
I've been studying some of the wiring diagrams at veryuseful.com and it appears that some of these lights might share a circuit, but I'm not the best at reading schematics so I have no clue where to begin checking things. Any advice?
Also, can someone tell me which wire in the radio harness is the "illumination" wire? I.e., when hooked up it will dim the display of my aftermarket headunit when I turn the headlights on? And which wire should I use for a switched (key-on) 12V?
