I've got a VQ37 as my engine swap project. It was an automatic so has the auto wiring harness and ECU. The ECU has Uprev on it and has a manual ROM etc.

I'm struggling to work out where the clutch switch should be connected so that I can use all of my UpRev ARC features. ECU Pin 41 looked promising so I have added a pin to this (was empty previously) and can see battery voltage being put out from the ECU on this wire. However, grounding the pin does not change the reported UpRev clutch switch value of 136 as I had hoped.

Anybody have any ideas where the factory clutch switch wiring goes ?!
