Hi. We purchased a 1997 Bathurst MR2 which has had a 3S-GTE Gen3 engine installed.
The first problem is the Fuel pump . There is a manual switch which switched the fuel pump, I'm trying to restore the "Circuit Opening Relay" (COR) operation.
I'm stuck with the wire from the OCR Pin 4 (Green/Red) back to the ECU FC Pin14 plug A (Green/white).
The wiring diagram I have shows this wire going only between these to points, But I have a Green/Red at the relay and a Green White at the ECU, I have metered these two wire and they are not joined.
The wiring diagram I have is for a 1993 3S-GTE model and its the only complete one I could find.
The Questions I have
1) Does anyone have a 1997 MR2 Full wiring detail.
2) On later models is there an intermediate plug for the Green/Red wire ? and where is it ?
