The fuel door release system contains the following components:

The FUEL DOOR relay switch and coil terminals are supplied with battery voltage at all times via the DOOR CONTROLS circuit breaker from the BATT 1 fuse. When the fuel door release switch is activated, ground is applied to the coil side of the FUEL DOOR relay. This energizes the coil causing the switch contacts to close. With the switch contacts closed, battery voltage is supplied to the fuel door release actuator, opening the fuel door. Ground for the fuel door release switch is supplied at G201 and the fuel door release actuator is provided ground at G301.
