An 82 ohm 5 watt resistor will trick the ECM. The two black wires of the O2 harness are the correct wires for the heater. On the ECM side, the red wire is +12v. There are two black wires, one is chassis ground for the O2 output and the other goes to the ECM to monitor current, this is the one to use if you are going to wire on the harness side. I'd suggest using the sensor wiring just in case you ever want to switch back. Solder the resistor to the two black wires (if you use the O2 sensor wires), wrap in electrical tape, and you're done. I think I paid about $1-2 for a package of two resistors. You do need the 5 watt power rating to avoid burning the resistor out and possibly starting a fire.
Hope this helps.

Jeff,
That helps a bunch. As soon as my knee gets better I'll get under there and set that up. Thanks
