i'm doing a ls/vtec in a EF. I wanted to know what you guys are doing for one wire o2 sensor. i do not want to put a hole in my headers so i was thinking of T-ing from a 5volt referance line with a resistor in series back to the ECU. If anyone has any ideas or if you would liike to share your setup it would be much epreciated.

Just use one of the sensors, and splice both wires into it.

So your saying send the signal from the o2 sensor to both inputs via a splice? Also, I'm using a OBD-1 harness on a PW0 ecu with a b16a1/b18a1 engine, does the ecu require a one-wire o2 sensor or a heated o2 sensor? The kid i bought the engine from had a heated o2 sensor in the headers. Thanks .
