In my ever present quest to locate parts for my GTCS, I purchased a headlight wiring harness ( the one that goes to the voltage regulator, headlights, marker lights etc). It was pulled from a 68 with a 302 and manual transmission.. The question I have is does this harness also connect to the brake distribution block, and if so what should the connector look like on the harness? Should it have 1 lead or 2..the harness I have has 1 lead, but my distribution block sensor has 2 leads. (The distribution block is a 68 disc brake block with proportioning valve). Is the harness different for a disc brake car?
