Chris' '90 Toyota
Celica All-Trac Turbo
(aka "The Shuttle") Autronic SMC Installation Details - Wiring |
Throttle Position Sensor Wiring. The stock Toyota TPS utilizes four wires, but the Autronic SMC uses only three: ground, a TPS feed, and the output wiper signal. The fourth wire indicates a closed throttle to the stock Toyota ECU. This wire is not used by the SMC.
