## Underhood Fuse Block Replacement Fuse Block

### Removal Procedure

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.
2. Remove the fuse block cover.
3. Remove the bolt from the fuse block bracket.
4. Release the clip and slide the fuse block (1) from the bracket.
5. Remove the 2 bolts and the battery positive wires from the fuse block. Note the correct terminal routing for installation.
6. Disconnect the electrical connectors from the bottom of the fuse block.

### Installation Procedure

1. Connect the electrical connectors to the bottom of the fuse block.
2. Connect the battery positive wires to the fuse block. Secure with the 2 bolts.
3. Install the fuse block (1) to the bracket. Secure with the bolt.
4. Install the fuse block cover.
5. Connect the negative battery cable.
