My TIT (ships gauge) was acting eratic. When my mechanic went to replace it the part he received was wrong. he had already removed it and I guess that was enough tinkering to break it. Having difficulty finding correct part. The wires are red and yellow and the battery switch must be on to get a reading. When looking at the wiring it appears that the shielding from the white wire is soldered to a ground. The wire is about 30" long and the probe is small in diameter (I believe fast response type). Did not measure clamp diameter but it is at least 2".
In summary:
red/yellow
grounded
clamp style
I am going to call KS avionics today
