Nicko,
The 175 should have a Blue/Black/shield bundle. Using the HF connector, Blue to pin-1, Black to pin-3 and the Shield (drain wire) to the chassis of the 295. The White and Brown wires should be the Temperature sensor. The temperature goes in on the six pin connector with White going to pin-2 and Brown to pin-3. Is you M-260 diplexed (two wire) or non-diplexed (four wires)?
