With a stock electrical system, the answer above is probably the only way. When key is turned on it merely grounds the coil, no power is activated. Your electric gauges require a hot wire to one terminal and the other terminal goes to each gauge separately. Don't expect much, or any, movement on the oil pressure ga. Have fun!
