Fuse Block #1: Operation
WARNING: This page is about a different car, the 2004 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
All of the circuits entering and leaving the fuse block do so through the instrument panel wire harness. Internal connection of all of the fuse block circuits is accomplished by an intricate combination of hard wiring and bus bars. Internal relays and micro processors allow the vehicle electronics to control some of the power distribution circuits throughout the vehicle. Refer to the SYSTEM WIRING DIAGRAMS section for complete circuit diagrams.
