2007 TBSS E67 TCC Wiring

[jnickell41]

I have read some conflicting information on Gen IV TCC wiring and have a question about my specific situation.

Engine and transmission are from a 2007 TBSS with E67 ECM.

I have included a picture of the ECM pinout as well as part of the wiring diagram I have been looking at.

The ECM pinout shows "TCC Brake Switch/Cruise Control Release Signal" on C1 Pin 2 Purple wire

The wiring diagram shows C1 Pin 2 as "TCC Brake SW" going to "Anti-Lock Brake System" I believe the CHMSL Supply voltage on C1 Pin 7 is used to disengage the cruise control

I have yet to start the truck, but I currently have C1 Pin 2 (TCC Brake SW) to hot with brakes off and C1 Pin 7 to hot with brakes on (CHMST Supply Voltage).

Having the TCC switch wired to hot while brakes are off seems opposite from some of the info I have read on Gen IV computers.

Any input would be appreciated.
