Temp sensor

I tried searching for answers but my problem is a little different. My bumper was ripped off and the sensor went with it. I have a pair of blue wires just hanging there and a few plugs dangling too. I know one plug is my fogs, the other I'm not sure, my question (finally) is what color are the wires that go to the temp sensor? This is all on the driver side of the car and I can see the wires easily when the tire is removed. I think the one blue wire has small white dots/lines on it also

your bumpers has about 3 connections.

1) Temp Senor
2) Horn
3) Fog

if you still need help I can show you pix of the temp sensor and how to fix it. My temp sensor was ripped off also and it only took me 10mins to fix it.

Horns are hooked up, fogs are disconnected but I know which ones they are, one is just flapping in the breeze but I'm not really concerned with it, just the two blue wires that are ripped apart and hanging there. Do you remember the colors of the wire when yours ripped off?

I went and picked up the new sensor and the connector. Does it matter which wire goes where? They gave me white wires to make a new harness out of.

Should not matter what wire goes where for this sensor.

Just finished hooking it up. FYI, the polarity does matter. One way I got +61 the other was +36. I used a cup of hot water to verify correct operation.
