What wire do i need to hook up the light in my autometer mechanical boost gauge? I wasn't quite sure how to search for this, and the searches i made came up with nothing real. I feel stupid asking this, but thanks.
There are a variety of ways to do this, either through the dimmer or otherwise. I did mine through the fusebox near the driver's side door. You'll just need to use a voltmeter to test the proper wires.
