Need help wiring FITech 70004 to brake switch
Working on the wiring connections for my FITech ECU and there’s a wire that needs to have 12v when the brake is NOT applied and zero voltage when the brake IS applied. I have the factory wiring diagrams for the brake switch but not sure which wire is the right one to connect to. Would I connect this wire to the purple wire that goes to the tranny?

Re: Need help wiring FITech 70004 to brake switch
Just following up as I figured this out. My brake switch had two connectors on it. One controlled the brake lights and the other worked the torque converter clutch. I removed the purple wire to the tq clutch and connected this to the FITech yellow wire for the TCC brake. This provides the correct signal for the ECU. Score!

Yup!
That's the Brake Pedal Wire (TCC) that My Horn blown by Brake-Pedal Prank Harness uses to Honk the Horn!
Install 2 Jumper Connectors:
-One at the Brake-Pedal Switch (TCC).
-One at the Steering-Column Connector (for the Horn Wire).
And an "Aligator-Clip" to attach to anything Grounded.
With the Engine running (or Ignition-Switch "ON")...
The Horn BLOWS anytime the Brake-Pedal is pushed!!!
