He had some of the wires backwards on the heater and ground signals. I think we got it figured out, but he hasn't gotten back to me.

I believe he had the two heater wires hooked to the two ground wires, the signal wire was correct, but had the ground reference for the sensor hooked to the power supply for the heater. Which would alter the voltage to ground resistance the ECU expects to see.
