Significant Technical Input
Rule of thumb: Whites are heater, black is ground, red is signal.

I just had to pull mine when I swapped out the propshaft.

I thought mine had two black wires and a white wire. I suppose one could have been a VERY dark red, but I don't think so.

Another rule of thumb: Three-wire sensors - Paired colors are heater circuit, odd color is signal.

Definitely only three wire, all three sensors are three wire. They have a four wire plug, but only three (3) wires.

hmm. They don't cover three wire instalation. Looks like you will need to email them. Interesting product, if you would let us know how this works out. . .

Your car does not monitor the Heater circuit. The wire labeled Heater is used to power the sensor to pre-heat it and send a signal to the ECU. In this case, if the heater wire shows +12v only when the ignition is on, use it as the power source to the sim.

this is the response i got so info for all. i still have yet to install. ty for all the help and i will update after intall.
