I have no idea why the temperature gauge doesn't work, I assume it works on resistance with a negative feed from the sender. If I apply a negative feed to the gauge wire the needle shoots up instantly to the max (hot), but with the sender wire it doesn't even move. The sender wire is also negative as I checked so maybe the resistance range is wrong?
Using an OEM cluster has saved me about 500 pounds as that is what a new set of gauges would have cost.
