There are two temp sensors, a two wire and a four wire, the lower sensor has four wires, the wires on mine were corroded off at the connector. I managed to find a new connector but I don't know which wire goes to which pin. This is on a 1988 80Q. Could one of you take a peak on your temp sensor and let me know which color wire goes to which pin.
Thanks for your help

I've looked in the wiring diagrams, but they only show a 2-wire temp sensor for the 88 80Q.

Not unusual for the wiring diagrams to be inacurite.

the upper sensor is a two wire, the one on the underside of the coolent outlet pipe has four wires. I can't seem to find a diagram, that is why I asked for some one to just take a gander at theirs.

He's talking about the MFTS.

Re: He's talking about the MFTS. Right, but its not in the wiring diagrams(Bentley) on 88 80Q!

Weird!!

BLU-BRN, "T", coolant temperature gauge
BLU-WHT, "R", A/C control head
BLK-BLU, "+", Fuse #12
BLU-YEL, "C", low coolant warning light

These are for 1990 90, likely the same for 1988 80Q.

Found it, It's called a temp switch, it is found on the wiring diagram for a 1987 coupe quattro(not a US model) right out of the bently manual. This is the CIS E III. Even the wire colors matched and the connector had the pin numbers molded right into it. Now if I could only get my temp gauge to work.
