1 wire o2 to a 4 wire?
i swapped a 94 ls motor in a 95 cx, everything works fine except the o2 sensor is wrong. how do i go about wiring the 1 wire to a 4 wire? i did a search, not finding what i was looking for.

SEARCH = couple of posts I found where I typed in the samething..........
White wire on O2 sensor is signal wire. Green wire is Signal ground. Both black wires are the heater circuit wires, and though someone has said that the polarity matters, I don't think so, or Honda would have made them different colors. One side goes to the heater circuit control, and the other goes to 12 volts switched power. The ECU grounds the heater circuit when it wants to turn it on.
Run O2 sensor signal (white) to D14
You can run the O2 sensor signal ground (green) to D22 (or any other good ground)
Run O2 sensor heater circuit control (black) to A6
You can run your O2 sensor heater circuit power (black) to A25/B1 (or any other good switched 12v source)
