For 1990-2009 cars

Battery voltage is applied at all times from the RH rear junction fuse block IP 1 fuse to the remote function actuator (RFA) module. When the ignition switch is turned to ACCY or RUN, voltage is applied from the IP fuse block WSW fuse to the RFA module. The RFA module senses when the ignition switch is turned to the OFF position. The RFA energizes the DAB ACSRY relay by grounding the relay terminal B7. With the DAB ACSRY relay energized, battery voltage from the RH rear fuse block IGN 1 fuse is applied in order to power the accessories. The accessories operate for approximately 10 minutes or until any door is opened. If any door is opened or if 10 minutes pass, the RFA module de-energizes the DAB ACSRY relay by removing ground from the relay terminal B7. This removes the power from the accessories. This 10 minute timed interval can be reset by turning the ignition switch to the RUN position, then back to the OFF position.
