I can only recommend to you to look for the Haynes Carina manual (about 15 pounds).

But here is what the wiring diagram says:

Pin 1 on the o2 sensor runs a blue/yellow wire to pin b1 on the fuel injection (FI) ECU.

Pin 2 on the o2 sensor runs a white/red wire to the circuit opening relay.

Pin 3 on the o2 sensor runs a screenend red/blue wire to pin C6 on the FI ECU.

Pin 4 on the o2 sensor runs a brown wire to pin C16 on the FI ECU

Hope this is enough to help you, but what is a halmeter?

Thank you very much for your answer..I'll try to figure out some things for it..A halmeter is an A/F Meter..Air/Fuel Meter..

Had it done some years ago and it's an ideal visual aid. Tap into the blue / yellow. If you're unsure put a voltmeter on each of the wires whilst the engines running and the lead you nedd is the one that's constantly moving between 0.1 and 1.0 volt. Easy
