question about downstream O2 sensor wiring
I have my swap completed and running, but am missing the downstream O2 sensor after the cat. without this O2 sensor, the car always runs way rich. my question/request for help is this:
I do not have a wiring diagram for a 96-97 OBD2 2JZ-GE and would like to wire up the downstream O2 sensor, but don't know if the wiring is in the engine harness, or if I need to run wires to the ECU. The motor is in a Mazda RX7 so no body harness.
Ayway, either of 2 things would greatly help:
1. someone who has a 96 or 97 SC300 please look and tell me where the wiring for their downstream o2 sensor originates (if engine harness, then I have that safely wrapped up in the undercarriage)
2. if wiring for said O2 sensor is not in the engine harness, can someone tell me what the pinouts are from the ECU so I can run my own wiring for it?
Any help here would be awesome!
thanks,
