OUTSIDE TEMP DISPLAY QUESTION

[300EVIL]

my temp display in my 87 300E no longer works. when it was working it displayed temps like +120 degrees ferinhight on 75 degree days. in the colder months it worked correctly.
one day it just stopped working completely. there is a cable cut that runs along the left side of the engine compartment.( not sure if this was possibly cut by a tech working on the car before I realized the gauge was dead) which is the same diameter cable used on the temp sensor located under the front bumper. this cable has 4 conductors,
dose the temp sensor have four conductors? the colors are I believe: red, green, black, and a bare ground wire. I cannot find the other end to this cut cable so I can't hook it up and see what starts working. anyone have any suggestions?

also, I was looking threw the parts shop tonight. great prices! anyway, I need the outside power window seal strips.
the horizontal rubber things that look and work like windshield wipers. this is the best way I can explain it.
can someone give me the part no.? I cant seem to find it in the search.
your comments and questions would be greatly appreciated!!
thanks,
Adam
