PCM Torque Converter Control I'm having trouble connecting my torque converter to the PCM. A little background: swapping an ’04 GTO LS1 into my '69 Chevelle. Bought the engine harness on the cheep, and got what I paid for - the line connecting the brake switch to the PCM to release/engage the torque converter wasn't supplied. Looking at Brendan’s pinouts (http://lt1swap.com/2004gto_pcm_pinouts.htm), the pin that seems to fit best is on the Green PCM, pin 5, “Delivered Torque Signal,” although pin 42 is “TCC Solenoid Valve Control.” I can guess at what these pins do, but really don’t want to screw up the tranny by guessing. I also don’t know if I need a relay for a low voltage connection to the PCM, or does it take 12v direct from the brake switch. Help!! Does anyone know the correct wiring?
Many thanks
