IP Compartment Lamp

When the IP compartment is opened, the Rear Integration Module (RIM) Inadvertent Power Input is grounded via CKT 149 (DK BLU/WHT) through the IP compartment lamp bulb, CKT 148 (DK BLU), the IP compartment lamp switch, and CKT 450 (BLK). In response to this input, the RIM energizes the INT LP relay to supply battery positive voltage (B+) via CKT 149 (DK BLU/WHT). The IP compartment lamp will light because it is receiving power and ground.
