Hi guys,
I am in the process of restoring my Mini for track use. I am running a SC 7 port fuel injection setup with their wiring harness & ECU. That is all good to go, however I am rewiring the entire car to bring all my fuses & relays to one place.. I am having a very tough timing locating a true wiring diagram that shows pinouts and where the wires go. The Haynes manual has helped a fair bit.
My question is, what wiring runs from the engine harness to the body harness? The car is a 1994 SPI from Japan that had A/C.
Wires I have determined so far... From back view of body connector
Pin 1 - Ignition Signal - White
Pin 2 - Starter Signal - White/Pink
Pin 3 - Light Blue/Green wiring goes to Pin 27 on SC Typhoon ECU - OEM pin 27 shows Org/Blk leaving ECU going to Stepper motor which is not been used...
Pin 4 - Fuel Pump Brown/Green
Pin 6 - White/Black wiring goes to Pin 29 on SC Typhoon ECU - OEM pin 29 shows Blk wire going to ground...
Pin 7 - Alternator Charging Warning - Brown/Yellow - not used, aftermarket gauge
Pin 8 - Oil Pressure Sensor - White/Brown - not used, aftermarket gauge
Pin 9 - Purge Valve Brown/Pink - not used. However SC diagram shows this wire going to Pin 28 on there ECU...
Pin 12 - Purge Valve Black/White - not used
Now wires I am expected to have a place for
Water Temperature (Haynes shows Green/Black wire going to ECU pin 5)
Tachometer - Haynes shows White/Black but it goes to ECU pin 25. Not like the white/black wire (pin 6 above) which goes to Pin 29 on SC's ECU
Any help is greatly appreciated. I have attached the SC Wiring diagram for reference, it states MPI loom however I was told it is the same.
Regards
