Connecting the Twist Machine Paddle Shifter 3 to a TCI Transmission Controller
Please familiarize yourself with the TCI installation guide before beginning. In general, the most important thing to keep in mind is the following from the TCI manual:
The TCU is configured such that it's possible to have fully manual upshifts and downshifts at the flick of a switch like a bumpstick. This works by first activating the manual mode with one switch to Terminal C. Once activated, the transmission can be bumped up (Terminal B) or down (Terminal C) through the forward gears via an On-Off-On momentary rocker switch. The connections are to be made as follows:
Terminal A (red wire) - momentary ground for bump down
Terminal B (yellow wire) - momentary ground for bump up
Terminal C (blue wire) - +12 volts to activate manual mode
Recommended Wiring to the Paddle Shifter Receiver
Paddle Shifter Receiver
Terminal A - Red
Pin 3 - White / Black
Terminal B - Yellow
Pin 5 - White / Red
Pin 4 - White / Green
Pin 6 - White
Connect the TCI blue wire to a switch that will provide 12 volts to the TCI unit when on. This activates the TCI unit for paddle shifting.
This 12 volt switch is not part of the Twist Machine Paddle Shifter system. The customer is expected to supply this part.
