This information covers the various standard and optional Power Distribution components used on this model. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
The power distribution system for this vehicle is designed to provide safe, reliable, centralized and convenient to access distribution of the electrical current required to operate all of the many standard and optional factory-installed electrical and electronic powertrain, chassis, safety, comfort and convenience systems. At the same time, these systems were designed to provide centralized locations for conducting diagnosis of faulty circuits, and for sourcing the additional current requirements of many aftermarket vehicle accessory and convenience items.
These power distribution systems also incorporate various types of circuit control and protection features, including
- Fuses
- Fuse cartridges
- Fusible links
- Automatic resetting circuit breakers
- Relays
- Flashers
- Timers
- Circuit splice blocks
The power distribution system for this vehicle consists of the following components
- Engine Fuse Block
- Underhood Accessory Fuse Block
- Illumination Control Module
- Relay Control Module
Following are general descriptions of the major components in the power distribution system. Refer to the owner's manual for more information on the features, use and operation of all of the power distribution system components.
DESCRIPTION - ENGINE FUSE BLOCK
All of the electrical current distributed throughout the vehicle is directed through the Engine Fuse Block. The Engine Fuse Block houses three maxi-type bolt in fuses. The Engine Fuse Block is located in front of the control module box, next to the windshield wiper solvent fill tube.
OPERATION - ENGINE FUSE BLOCK
All of the current from the battery and the generator output enters the Engine Fuse Block through the cable and eyelet that are secured with a nut to the Engine Fuse Block B(+) terminal stud located on one end of the Engine Fuse Block housing. The Engine Fuse Block terminal stud cover is unlatched and opened or removed to access the Fuses.

- Move the wires away to the side of the box to access the clip (1) that holds the relay control module in the control module box.
- Push the clip (1) back away from the relay control module and lift the relay control module out of the control module box.
- Remove all of the relay harness connectors from the relay control module.
INSTALLATION - RELAY CONTROL MODULE
- Install the relay control module harness connectors to the relay control module (1).
- Install the relay control module into the control module box, pushing the relay control module down until the clips snap into place.
- Install the control module box lid.
- Connect the negative battery cable.
DESCRIPTION - UNDERHOOD ACCESSORY FUSE BLOCK
The Underhood Accessory Fuse Block houses many of the fuses for the vehicles electrical system. The Underhood Accessory Fuse Block is located on the left side of the engine compartment just in front of the brake booster. The Underhood Accessory Fuse Block can not be serviced it must be replaced as a unit.
OPERATION - UNDERHOOD ACCESSORY FUSE BLOCK
All of the circuits entering and leaving the Underhood Accessory Fuse Block do so through separate wires. There are NO separate wiring harness connectors that connect to the Underhood Accessary Fuse Block. Each circuit is connected individually to the Underhood Accessory Fuse Block, and held in place by the use of retention combs.
Scheme 43

- Remove the lid to the underhood accessory fuse block.
- Push the front of the underhood accessory fuse box forward releasing the tabs (1) on the underhood fuse block.
- Pull the underhood accessory fuse block out of the box and remove all of the underhood accessory fuse block harness connectors.
INSTALLATION - UNDERHOOD ACCESSORY FUSE BLOCK
- Install the harness connectors to the underhood accessory fuse block.
- Push the underhood accessory fuse block down into the box until the rear tabs and the front two tabs (1) connect.
- Install the lid.
- Connect the negative battery cable.
DESCRIPTION - FUSE BLOCK
The Fuse Block is part of the Illumination Control Module. A knob on the face of the module controls the exterior lighting functions. The exterior lighting and headlamp switch portions of the Illumination Control Module cannot be adjusted or repaired. If faulty or damaged, the entire module assembly must be replaced as a unit. Refer to REMOVAL .
OPERATION - FUSE BLOCK
