Plug-and-play 30-foot harness connecting Cummins Onan QG Series LP and gasoline generators to Onan remote control panels. 5-wire sealed connector. Sold individually.
The Cummins Onan 338-3489-02 is a 30-foot, 5-wire wiring harness that connects a compatible Onan remote control panel to an Onan QG Series LP or gasoline RV generator, enabling start/stop control from inside the RV. It mates directly with the sealed remote connector on the generator and the connector on the remote panel — no additional wiring required.

Sealed connectors at both ends mate directly to the generator and remote panel — no field wiring required
Up to 30 feet of routing distance between the generator compartment and the remote panel inside the RV
Carries all signals required for remote start/stop panel operation with compatible Onan QG control panels

This harness requires the sealed remote connector introduced on later spec generators. It is not suitable for MicroLite KV Spec A–E or MicroQuiet KY Spec A–E generators, which lack this connector. Check your generator's spec letter before ordering.
Backed by a 90-day limited manufacturer's warranty against defects in materials and workmanship.
Not compatible with KV Spec A–E or KY Spec A–E generators. Always confirm your generator's complete model number and spec letter before ordering.
