Battery voltage is supplied to the accessory power inverter module from the 25-amp ACPO fuse located in the auxiliary fuse block. The accessory power inverter module is grounded to the right rear D-pillar. When the engine is running, voltage, supplied by the FWD fuse, is supplied to the plug-inserted switches in the accessory power outlet. When a 115-volt AC-powered device is plugged into the outlet, the normally-open plug-inserted switches, located internally in the accessory power outlet, close. The accessory power inverter module detects a voltage signal on the control circuit and the accessory power inverter module supplies 115 volts AC to the accessory power outlet after a 1.5 second delay. The LED on the outlet illuminates to indicate that the outlet is powered.

The neutral circuit is isolated from the chassis ground. There is approximately 58 volts AC between either the hot or neutral circuit and the chassis ground. There is approximately 115 volts AC between the hot and neutral circuits. The ground terminal of the outlet is not used.
