I need to know if I can access Parking Light(+)wire from under dash? Most posts here indicate only from engine compartment fuse block. I don't want to have to pass thru firewall.

Thanks

Have you checked at the tail lights? It's not under the dash, but it'd be simple enough to test.

My ex once told me I have a perfect face for radio.

From looking into this further, I have a feeling that the parking lights are "switched ground" for this GM vehicle. This would explain why only the neg(-) comes out of the BCM under the dash. The tail light pos(+) could be camped-on to another ckt already at the rear? Just a guess.
