This IC panel shows how power flows through the three-gauge gas, oil, and temp circuit. Terminal A is Power In to the gas gauge voltage regulator, then to the gas gauge bi-metal bar in B. B feeds power to D (Power In to the temp gauge) and F (Power In to the oil pressure gauge). Power flows through each gauge and to the sending unit through the sending-unit terminal. C represents the gas-gauge sending-unit terminal. The temp gauge is E and the oil-pressure gauge is G.
