Inside the Kenworth front chassis wiring
- Bill of material: connectors, terminals and splices
- Chassis Power Distribution Center assembly (P93-1023-006)
- Terminal information by connector (Molex, Deutsch, Packard)
- DEF, SCR, NOx and ammonia sensor circuits
- Chassis node ports and CAN circuits
- Harness variations table (P92-4018-000)
Marked proprietary to PACCAR and dated 2009, the drawing is a full bill of material and circuit map for the front chassis harness. The material list enumerates Molex, Deutsch DT, DTP and HDP20, Kostal 53- and 86-way, AMP MCP and Packard Metri-Pack and Weather-Pack connectors, terminal bussbars, splices and the chassis power distribution center assembly and housing with its Cummins label. Terminal information tables give the circuit number in every cavity, including the engine and NOx power connectors, chassis node ports and the J1939 terminating resistor. A large block details the EPA 2010 aftertreatment wiring, listing DEF metering valve, DEF pressure, pump PWM, tank temperature and level, SCR inlet temperature and A, B and F CAN circuits with wire gauges. A harness variations table then keys each part-number suffix to sleeper length, trailer and axle options for T470 and T660 chassis.
Applicable truck models
The drawing is proprietary to PACCAR and lists connectors such as the Kostal 86-way, Deutsch HDP20 and Packard Metri-Pack series, plus DEF metering-valve, SCR inlet temperature and A/B/F CAN circuits. A usage note applies it to T470 and T660 chassis. Verify coverage against your VIN and build sheet on the Kenworth official website.
Who needs the Kenworth front chassis wiring
Chassis-electrical technicians use this diagram to trace power distribution, CAN data links and Cummins EPA 2010 aftertreatment wiring, and to select the correct harness variation for sleeper, trailer and axle options on Kenworth trucks.
