Reverse Harness

Two engine harness pins T10/5 and T3au/1 carry the reverse circuit. You must populate these pins on the engine harness and make a harness to plug into the transmission. The transmission plug is a simple switch, polarity is not important in this case.

Clutch to ECU

Engine harness pin T15/13 should be tied to the ECU pin 39.

Method: One can use the red connector wire from T15m/5 (black/purple) to populate white connector T15/13. Then move pin 30 on ECU connector (black/purple) to pin 39 on ECU connector.
