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
