Inside the Kenworth park tail lamps
- Connector information for diagram P94-1590
- Terminal information by part number (Deutsch, Packard, Eaton M/P)
- Circuit position charts (K333, Truck-Lite connectors)
- Headlamp harness detail views
- Tail lamp assembly details and backup lamps
- Sleeper extension and junction box details
This is a diagnostic wiring package rather than prose, organised into three linked tables. The connector list details every reference designator with its cavity count, part number, description and physical location, from the Deutsch HDP 20 and HDP 30 plugs at the power distribution box to Eaton Metri-Pack 630 switch connectors and Truck-Lite lamp bodies at the fenders and tail assemblies. The terminal information tables map each connector cavity to a circuit and wire number, showing the brown L1PL park-lamp, R1PL tail-and-park and green or yellow turn circuits, with ground returns landing on the firewall studs. Circuit-position charts illustrate every connector face, and detail views add the headlamp harness, Truck-Lite tail lamp assembly, sleeper extension harness, frame-mounted junction box and an additional seven-way trailer receptacle option.
Applicable truck models
The diagram lists connectors such as the black Deutsch HDP 20/30 at the PD box, Eaton M/P 630 switch connectors and Truck-Lite tail lamp connectors, with the L1PL park-lamp and R1PL tail-and-park circuits. It is used on W9, T6, T8 and C5 chassis with NBI and Namux I instruments. Verify coverage against your VIN and build sheet on the Kenworth official website.
