Help Needed: Heated O2 Sensor
I just bought a Bosch 13077 heated O2 sensor to install in my car. I think $25 is kind of ridiculous to pay for the harness that is made for our vehicles with a heated O2, so I planned on hooking it up myself using the 1 wire harness from the old O2 sensor, spade connectors and heatshrink. However...
I can't find anywhere which wire goes to what on this thing. I have two white wires and a black wire. I know one wire is for the signal, one is power to the heater and one is heater ground, but I can't find ANYWHERE which wire goes to what. The 3 wires on the harness are labeled A, B and C but I still can't find anything that points to the function of each wire.
Could someone please point me in the right direction?

Re: Help Needed: Heated O2 Sensor
The install is pretty simple Ive done it on my car. Remember that the power wire needs to go to an ignition on power source.
