Looking at the wiring schematic now it's pretty straight forward. Black with Yellow trace from the light switch, plugs into the Black/Yellow under the dash at the main harness, then plugs into the the Black/Yellow on the engine side of the firewall up to the parking lights or front crossover wire harness. I either have some wires crossed at the firewall or the light switch is bad. Still confused why when I hook the Black/Yellow together from the light switch into the Black/Yellow under the dash at the main harness, why the dimmer switch has anything to do with interfering with the parking lights?
