help please

I stripped out my oem ecu and engine harness and engine and sold it to someone doing a 1.8 vvt swap to a 1991 and found that the harness interfaced to the body / remainder of the car at one single point under the steering column - almost like midway on the harness if the ecu is on one end and the engine connectors the other just before the firewall split

I kept this blue connector as i envisaged it would carry

switched positive
tach from ecu to cluster
signal to fan relay into harness
ac request signal
water temp to cluster
fuel pump relay request
oil pressure signal

etc etc

and it would make a great connector for my ms3 to fire all that into the oem environment

i am stuffed if I can find what those wires do - the only one i can identify is the white with red ! anyone have a pinout / colour description or similiar

has someone decoded what each wire does ? I really dont want to interface elsewhere and in parallel if i can make this as plug n play as i suspect it can be done - anyone done this before ?

Help please
