Wiring diagram of the instrument panel with a digital speedometer needed

Good afternoon,

I attached all the diagrams and pinouts I could find.

I hope this helps you.

You see, I probably fell off the mass, as the coolant indicator (thermostat) and the fuel level in the tank do not work . Because the arrows do not move in any way under any conditions!

I so understood these 2 device.

Okay, as far as the fuel sender, disconnect the fuel sender at the tank. The gauge should go to empty or full. Then ground the wire and the gauge should go the other way. That will test the gauge. If it does not work, then check for around 7 to 9 volts at the wire for the sender. If you do not have it, it is either the cluster or wiring.

Same for the temperature sender. Remove the sender switch wire and check the gauge and then ground the wire as well.

Sorry I not understood, (I poorly know English) on tank goes three wires : 1.black-ground for sensor and pump 2.white on pump and 3.purple on the sensor in the tank.

The purple wire is the one you do the checks I suggested.
