the most simple setup is to run a wire from the + side of the TCC solenoid to power thru a switch.

With this setup it will greatly extend your stopping distance at highway speeds. Because you will have to drag down the motor and the vehicle with the brakes till the vehicle wheels go below shift speed to 4th. I would do the same thing but include a brake switch with the connections for the brake lights and the unlock for the converter. Run the wiring through the switch first. However it will work both ways. I just prefer the fastest stopping distance possible.
