S13 SR20DET in S14 chassis

OK I found my knock sensor unplugged from the guy I bought the car from...I found 2 different plugs coming off the injector harness one was 4 wires and the other one was 2...i looked at the wires going into the 2 wire connector and they were white and black but turned a orangish brown color and black like an inch before the connector(had been wired in like that cause it had shrink tube on it)...but anyway i was curious as to the physical location of the connector for the knock sensor...does it come off the injector harness or what harness? I looked for a good 30mins(from the top side of the motor while feeling around) and i couldnt see anything other than those 2 connectors unplugged...so help a brother out...

Thanks,
Tony

the 4 wire plug is for your aac valve(idle air control valve) the 2 wire plug with the white and black wire is for your knock sensor
