2001 Monte Carlo LS.
I just put an aftermarket radio in my car. I unhooked the battery before i started. Used correct harness adapters and ran the red 12V switched wire to the 10A cig/aux fuse in driver side fuse box. Put everything back together, hooked battery back up, and started the car. Stereo works fine, but now my headlights, brake lights, windows, door locks, and turn signals/hazards do not work. I found only one fuse burned out and it was for the door locks. Im beyond baffled. Any help is appreciated. This is my only vehicle and i need to figure this out ASAP.
Thank you
