I did a small writeup on the AAN loom into a cq but it has some amendments needed....
Oil temp sensor wire to Aux Gauge is Black/White (pin 2)and the plug for gauges is this one:
Oil Pressure switch has two wires (has two outputs) For the gauge its this plug.
Blue/Black (Pin 5)
White/Grey (Pin 6)
Coolant Temp Sensor (G62) Green/Black wire that goes to ECU pin 45. This also goes to Altitude sensor F96. Its a white two pin plug on back of cylinder head.
If you need any more pics i still have full loom laid out in spare room so can photograph connectors etc. Hope this helps.
