Power is available to the headlamp and panel dimmer switch at all times
from the PK LMPS fuse 9 through CKT 240 (ORN).
Once the switch is turned to either the park lamp or headlamp function,
parade dimming is capable through CKT 1382 (PPL/WHT) to the
illumination lamps of the following components:
| • | Transfer case switch transfer case controls |
Power is also available for controlled dimming through the rheostat
to the ILLUM fuse 14 through CKT 44 (DK GRN)
