wiring advice

My 72 Demon had "selective surgery" of the underhood wiring done on it when I got it. I opted for YO harnesses for the car. The /6 and LA motors use the same harness, but I think a BB car would need a different one. If you go this route, recommend a thorough cleaning of the bulkhead connector. It can get corroded up which affects the accuracy of the gauges as well as operation of the headlights.
