Overview – Wiring Harness 289-9354
289-9354 is the cable wiring harness assembly used on CAT (Caterpillar) 120K, 140K and 160K motor graders to distribute power and signals across the frame, cab and engine electrical circuits. We can supply this wiring harness as well as related CAT electrical components, in stock or available on order – welcome to enquire by part number.
Parts Characteristics
The harness is built to the original routing and connector layout, with the wire gauge, terminal types and protective sleeving matched to the CAT 120K, 140K and 160K machine. Each branch is cut to length and terminated with the correct connector shells and seals so it plugs into the original components without adapters. The outer wrap and grommets protect the conductors from abrasion, heat and moisture in the frame and engine bay. As an OEM-spec assembly, it restores the original electrical performance and simplifies fault tracing.
Applicable Models & Applications
This wiring harness is used on CAT motor graders including the 120K, 140K and 160K series, where it connects the cab controls, engine sensors, lighting and implement circuits. Typical applications cover the main frame harness, cab harness and engine harness sections on both standard and all-wheel-drive configurations. Confirm the connector layout and branch arrangement against the harness removed from your machine before ordering.
Maintenance & Replacement
A damaged harness shows up as intermittent electrical faults, blown fuses, sensor reading errors and starting or charging complaints. Inspect the routing periodically for chafed insulation, corroded terminals, melted connectors and broken cable ties. When replacing, disconnect the battery first, label each connector as it is removed, and route the new harness along the original path, securing it at every clip point. Verify all connectors lock fully and that the harness is kept clear of hot exhaust and moving components.
Price Reference (USD)
The reference price for this Wiring Harness (289-9354) is approximately USD 120 – 480 per unit depending on section, grade, quantity and shipping destination. This is a planning estimate only – confirm current pricing and availability with our sales team before ordering.
Value & Service
A mismatched harness can cause hard-to-find electrical faults, so we verify 289-9354 against the original CAT routing and connector list for the 120K, 140K and 160K grader before dispatch. We can supply the harness together with the matching relays, switches and cable ties in one tracked order. Our team will confirm the correct section and connector layout for your machine before you buy.
