The Power Distribution Center (PDC) is serviced as a unit with the engine compartment wire harness. If any internal circuit of the PDC or the PDC housing is faulty or damaged, the entire PDC and engine compartment wire harness unit must be replaced.

NOTE: If the power distribution center (PDC) is being replaced with a new unit, be certain to transfer each of the fuses, fuse cartridges, fusible links and relays from the old power distribution center to the proper cavities of the new power distribution center.

Position the PDC over the mounting bracket in the engine compartment.
Align the PDC mounting slots with the blades on the PDC mounting bracket.
Push down firmly and evenly on the PDC housing until it snaps into place on the PDC mounting bracket.
Route the engine compartment wire harness from the PDC through the engine compartment, engaging each of the harness retainers to the mounting provisions in the vehicle body and chassis components. Make sure to make clip attachment into the rail located behind the PDC.
Install and tighten the fasteners that secure each of the engine compartment wire harness ground eyelets to the vehicle body and chassis components.
Reconnect each of the engine compartment wire harness connectors.
Torque nut retaining positive battery cable at PDC to 96 - 141 N.m (85 - 130 in. lbs.).
Reconnect the battery negative remote cable.
