pretty sure the sheilded wire is your ox wire.
black is your ground
two white ones are your heater ones
best thing to do is to map them out with your multimeter from your ECU to the wire under the car. Thats how I did my blacktop oxy as the motor didnt even come with a plug for it.
if your really stuck try emailing hsvmaloo_r8@hotmail.com (rhys) he has a 4agze in his ae92 seca and he knows quite allot about them.
Not sure if this will do the same with the gze but my age needed the ECU to be reset (disconnecting (-) from the battery for 20 seconds)
