Power to the gas gauge is received from the switched side of the ignition switch which means the gauge only works when the key is on. 2. Another wire goes from the other terminal on the gas gauge to the sending unit. This wire does not have voltage on it. It reads Resistance from the sending unit which is determined by the float in the tank. This resistance makes the needle move.
