02 sensor wiring help....
SOHC Civic. On my secondary 02 sensor, one wire grounds it, one drives it, one is for the 02 heater, but I can't figure out what the fourth one is for. I need to know because I had to wire one straight from the ECU. My HELMS tells what three of the four are for my secondary (red/white, green/black, white/black) but the fourth wire from the sensor is black/yellow and I can't figure out where it goes. I really don't feel like guessing with electrical stuff. Three of the four are wired and I need to know this ASAP. TIA!!!!
2 are for the heater

So I can wire the two heater wires together coming from the sensor, connect them to the one wire coming from the ecu, and it will work fine and I won't throw any codes?
