A. Inspect Engine Wiring Harness For Proper Routing

1. Locate the portion of the engine wiring harness which connects to the two (2) 10-way connectors on the bottom of the power distribution center (PDC) and to the 40-way connector on the powertrain control module (PCM) (Figure 1).
2. Remove the PDC from its mounting bracket.
3. Inspect the harness routing as follows:





a. The take-outs for the two 10-way PDC connectors must be routed above the heater hoses and EGR tube and secured in the clip located on the inboard side of the PDC (Figure 2).
b. The take-out for the 40-way PCM connector must be attached to the speed control servo bracket (if equipped) or the transmission mount support bracket (Figure 1).

NOTE:
On DOHC engines, the heater hoses are located below the EGR tube.

4. If the wiring harness is not routed as described above, continue with Step B. If the wiring harness is routed correctly, reinstall the PDC and no further action is necessary.
