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?
Seth, the only way the dimmer could be involved is in the wires at the front of the car. If the high beam wires are mixed up with the parking light wires the dimmer would send power to the parking lights rather than the high beams when the dimmer is switched from low to high.
