Pull the passenger dash speaker, the wires run down the passenger side windshield pillar and (I just pulled the lighted mirror and wiring from a parts car) the connector will be in that area.
Try'n to remember, it may be farther down by the computer because it connects up to the switch in the door jamb,
I've pulled so much 'stuff' from this car it gotten hard to remember.
Thank you. That gives me someplace to start. I installed a Pro-M processor (recommended!) several years ago and in the process, lost my interior lights.
