Hello,
I recently purchased a rear window defogger for my 69 Camaro. I want to keep the wiring as close to original as possible. My question… would the factory have these connections bundled into the main dash trunk etc harnesses? Or would they have used what I’ll call an accessory harness like you would buy from American auto wire and others.
There are even some GM new old stock harness that resemble the American auto wire stuff. They plug into the dash switch, and a 12 volt accessory port on the fuses block to make it work. Did the factory do our cars this way?
On my car there are a number of empty pin positions In the factory dash harness where it splits off towards the rear of the car, just behind the headlight switch. Makes me think these pins would have been utilized for an instance like mine.
