When the ignition switch is in the RUN or START positions it applies power to the gauge fuse, located in the junction block 2. Current flows from the fuse to the multifunction alarm module and out through the RED/BLU wire connected to C2 cavity 9. Continuing to junction block 3 C3 cavity 5, to junction block 3 C4 cavity 4, to SP258, finally going to the backup lamp switch cavity 2. When the switch is closed it allows voltage to be applied to junction block 1 C3 cavity 9 through backup lamp switch cavity 1, which leaves the junction block at C5 cavity 4. After leaving junction block 1 C5 cavity 4 current is split through SP450, to the rear combination lamp cavity 4. Ground is finally provided at the rear combination lamp cavity 5.

When the ignition switch is in the RUN or START positions it applies power to the gauge fuse, located in the junction block 2. Current flows from the fuse to the multifunction alarm module and out through the RED/BLU wire connected to C2 cavity 9. Continuing to junction block 3 C3 cavity 5, to junction block 3 C4 cavity 4, to SP258, finally going to the park/neutral position switch cavity 4 (4 SPD A/T) or 6 (3 SPD A/T). When the switch is in the park position it closes and allows voltage to be applied to SP260 through park/neutral position switch cavity 5 (3 SPD A/T) or 8 (4 SPD A/T). SP260 applies voltage to the powertrain control module and also junction block 1 C3 cavity 9, which leaves the junction block at C5 cavity 4. After leaving junction block 1 C5 cavity 4 current is split through SP450, to the rear combination lamps cavity 4. Ground is finally provided at the rear combination lamp cavity 5.
