I've been spending time laying out my Painless wiring harness for my '55. I have a TPI engine and 700R4 transmission from a 1985 IROC. In the instructions it states that if I am using the lock-up circuit I am going to need a brake switch that is CLOSED (electrically connected) when the brakes are NOT applied and OPENED (NOT electrically connected) when the brakes ARE being applied. This is opposite of a standard brake light switch. Now, I don't claim to be brilliant, and I can follow directions well, but this is my first wiring job that includes a computer. So, what would be a brake switch I can use?
