Refer to Wiring Repair in Wiring Diagrams for the location of the wiring repair procedures.
1. Remove the PDC housing lower cover.
2. Remove each of the relays from the PDC relay wedge to be removed.
3. From the bottom of the PDC housing, use a small screwdriver or a terminal pick tool (Special Tool Kit 6680) to release the two latches (yellow) that secure the relay wedge to the PDC relay cassette.
4. From the top of the PDC housing, remove the relay wedge from the PDC relay cassette (Fig. 5).

1. From the top of the PDC housing, align and insert the PDC relay wedge latch arms into the correct cavities in the relay cassette.
2. Gently and evenly press the PDC relay wedge down into the relay cassette until both of the latches are fully engaged.
3. Install each of the removed relays into the proper cavities of the PDC relay wedge.
