940 Temp Gauge Compensation Circuit--How to Disarm 900

I wonder if anyone has suggestions on how to rewire the gauge to go around the compensation function.

I just pulled a temperature gauge from a 1995 940 NA to try to investigate how the temperature compensation circuit works.

The gauge connects to the instrument panel's flexible circuit board through four threaded mounting posts (each secured by a small phillips screw).

On the gauge circuit board, one post attaches to a trace that is labelled +--this might be positive;

two posts attaches to a trace mark - (this might be negative); and

another attaches to a trace marked U.

I posted an image here:

Based on the wiring diagram, I see that the gauge is attached to battery voltage, ground, and two other wires, one of which I assume goes to the sender.

I Wonder if I could wire the sender directly to two of the posts--or if I need to disconnect the circuit board.

Thanks,
pmp3
