This is a new, genuine Kubota injector wire harness, part number 1J770-65270. Kubota describes it as “HARNESS, WIRE, ASSY (INJ)”. It carries the 1J770 prefix, the same number series as Kubota’s V3307 common-rail injectors (for example 1J770-53050 and 1J770-53075), but we have not found a Kubota where-used list for this harness.

Injector harnesses are replaced for chafed or heat-damaged wires, broken connector latches and intermittent injector circuit codes. Check the codes and test the injector circuits with a meter first, since a failed injector coil or an ECU fault can look the same.

Fits / Applications

• Direct replacement for a Kubota injector harness numbered 1J770-65270

Disconnect the battery before unplugging injector connectors. Route the harness in its original clips away from hot and moving parts, check every connector seal and latch, and clear stored codes after the repair.
