    I alright guys I'm wiring up some gauges in my 94 GT. I need to find the dimmer wire to tap into. Anyone have some wiring schematics for a 94GT headlight switch. I can find every other one but the schematic for that. I'm having a hard time finding what I need tap into for the dimmer wire. Anyone got a schematic? I think it's the blue/red wire but want to verify.

    I thought it was Red/yellow but my brain is foggy. If you're testing at the hdlight switch, turn on the parking lights and find the wires that have 12V to them in the parking light position (omit the constant power feed to the switch). Now run the dimmer up and down with your test light connected to each of those hot wires and see which one dims.

    Depending upon what you're tapping into that circuit, you could grab it at the fog light switch or any place else that has a dimmed light.

    Good luck.

    Blue wire with the red stripe, and I'm absolutely positive on that one. The easiest place to access it is on the radio harness.

    Light blue w/red stripe is common to all dash illumination bulbs. What is the application, gauges?
