I'm trying to finish up the wiring and I need to hook up the TCC Ground wire. It's the one that has 12v at all times then 0 volts when you hit the brakes. How are you guys getting to the brake switch? I can barely even see the thing? Is there somewhere else you're hooking into? My truck is a 95 w/t.
It needs 12 volts ignition power at all times, until the brake is pressed. Then it needs to cut power while the pedal is pressed down. Just get a test light down there on the brake switch and start pressing the pedal
I can't even get my hands to the switch. It's on top of the brake pedal arm. My hands are too big.Quote:

If the wiring is the same as on my 92 c1500 there should be a brake signal wire that goes to the old ecm. It's a purple wire that runs to the C207 connector that splices into the engine harness behind the glove box.
