    Ambient Air Temperature Sensor

    I have a 2005 BMW 325i, I realized my sensor was missing so I bought a new one. I have run into the issue of finding the 2 wires that it connects to. For some reason my wiring harness is a little jacked up and many of the wires are independently hanging.

    All the wires are on the harness i just need to know the color to the 2 wires that go to the sensor in order to solder the new sensor in.

    The orientation of the wires is meaningless. It's merely a trermystur, a resistor that changes it myself resistance when it's temperature changes.

    Well it's reading +122, and as I've read on most forums I believe the wires are touching somewhere.
