I'm pretty sure the the two blacks are power. One sensor the other for the heater. The two white are grounds. if my memory serves me, write. I'll check my car next time I'm around it and snap pix of the harness and sensor connection.

I can't remember of my head but pretty sure the.1g 2 white wires & 2g 2 black wires. And,the other two use a voltmeter to test the,wires. Sensor wire uses,five volt reference and heater is 12v. So if key is on sensor wire, should read 5v from harness when unplugged.
