Cool, I have a spare brake light switch floating around that I can use. I suppose I should have thought of that by now, or at least before I put the pedals in :(
Thank you Sirs!
You don't need to use the auto trans harness , it just would connect to the starter relay where the wire from the auto trans harness connects . Or you can just connect that terminal on the relay directly to ground , thats how it was prior to 1970.
