Schematics
On a vehicle with an automatic transmission, see
Fig. 1 for a schematic of the engine wiring between
the PLD control unit and the bulkhead connector. For
a detailed (partial) schematic of the wiring to the
transmission electronic control unit (ECU), main power
distribution module (PDM), engine fan, low coolant
probe, and intake-air heater (optional), see Fig. 2.
For a detailed (partial) schematic of the wiring to the
bulkhead module (BHM), see Fig. 3.
On a vehicle with an automatic transmission, see
Fig. 4 for a schematic of the cab wiring between the
bulkhead connector and the vehicle control unit (VCU),
including the devices attached to the dash harness.
For a detailed (partial) schematic of the wiring for the
engine protection system, see Fig. 5. For a detailed
(partial) schematic of the wiring for the cruise control
switches, panel lights, and engine fan switch, see
Fig. 6.
On a vehicle with an automatic transmission, see
Fig. 7 for a schematic of the J1587 and J1939 datalink
wiring.
On a vehicle with a manual transmission, see Fig. 8
for a schematic of the engine wiring between the PLD
control unit and the bulkhead connector.
On a vehicle with a manual transmission, see Fig. 9 for
a schematic of the cab wiring between the bulkhead
connector and the vehicle control unit (VCU), including
the devices attached to the dash harness. For a
detailed (partial) schematic of the wiring for the engine
protection system, see Fig. 10. For a detailed (partial)
