Put in a regular relay with the LU circuit Teed into on the 30, and 87 terminal to ground. Then put power to the 85 and 86 goes to what ever triggers it, then to ground from the trigger. Clear as mud? If not I'll see if I can hallucinate it better for you.

My only problem is when I manually lock the tcc at lower speeds (lower psi) and forget about it when stoping (ground is tied in with the brake switch). Makes for some excitement at a stop sign or red light

I wouldn't want it to unlock going down a hill. I have a 47RE in my '97 so I have some experience with how it functions. .
Philip wrote:The one concern I would have with using the TPS for that control. The TPS only sends a reference signal to the PCM. The relay your wanting to use doesn't use much power for the pull in coil. But is the TPS capable of standing an actual voltage draw threw it?
A mechanical switch rigged to the throttle pedal like a jack brake idle switch would work. You could mount the switch to trip at what ever throttle position you wanted. You would be using a full 12 volts for it. No special relay needed.
