If you are replacing the OEM rally fuel gauge, you may want to consider doing the solid state IVR upgrade.
The OEM uses an archaic mechanical voltage limiter integrated in the fuel gauge to supply the 5-6 ish volts needed to run the other gauges (Not amp gauge). By defeating the switching effect in the gas gauge, and using a solid state voltage limiter in it's place, you reduce the chance of a closed failure supplying full voltage to your gauges and frying them.
***EDIT*** Disregard the red and black jumpers......They power the ammeter to voltmeter conversion.
