so this will be the method i use to wire my TCC Brake switch. Since i will be using the standard 4L60e tranny harness, you only need one wire to tell the PCM when u are stepping on the brake.. blue connector, pin 33.
since i am redoing the brake system from scratch i don't have a brake switch on the pedal i have the pressure activated type on the proportioning valve. I need to run a Standard bosch 5 pin relay.
85 - ground
86 - to brake wiring on car.
30 - to IGN + 12v
87a - to tcc wire/PCM
The TCC wire is located on the blue connector pin 33
