TCC hook up on 04 GTO PCM?

I need to know which wire to use for a tcc hook up. The 04 gto pin out list 2 different tcc wires

GY/RD 422 TCC Solenoid Valve Control

BN 418 TCC PWM Solenoid Valve

I would guess this is like others 12v until braking then 0v. Which connection and what's the other wire for?
Are there any wires on the transmission that I will need to check or modify?

Thanks

Jweb,

Looking at the diagrams on lt1swap.com I think both 422 and 418 go to the transmission to control the TCC solenoid.

I think the brake switch signal you are looking for goes here on C1-33

It looks like its wired as a normally closed switch, so 12v off the brake and then 0v when brake applied.

Looking at the pinout that wire is for the cruise control. I wonder if does both?
