Remote start/stop switch panel with hourmeter and mounting plate for compatible Onan gasoline and LP vapor RV generators without diagnostics.
The Cummins Onan 300-4937 Deluxe Remote Panel provides a convenient interior control point for compatible Onan RV generators. Instead of starting or stopping the generator directly at the generator compartment, this panel allows remote start/stop control from an installed location inside the RV.
This deluxe panel includes an illuminated start/stop rocker switch and hourmeter, making it easier to monitor generator runtime for service tracking. It is intended for compatible Onan gasoline and LP vapor generators without diagnostics, including commonly listed CM QG 2500/2800, MicroLite KV, and Camp Power KVD applications.
Illuminated rocker switch allows remote generator start and stop control
Tracks generator run time for maintenance and service intervals
Designed for compatible Onan gasoline and LP vapor RV generator applications
Includes panel assembly, mounting screws, and instruction sheet with template
This remote panel is not universal for every Onan generator. It is listed for Onan gasoline and LP vapor generators without diagnostics. Before ordering, confirm your generator model, spec letter, and existing remote wiring setup. This panel does not include a wiring harness or fuse. If your RV is not already wired for a remote panel, or if the original harness is missing or damaged, additional wiring parts may be required.
Before Starting: Turn off generator power and follow all RV/generator electrical safety precautions before working with remote start wiring. Basic Installation Steps: 1. Confirm Compatibility: Verify that your Onan generator model is compatible with remote panel part number 300-4937. 2. Check Existing Wiring: Confirm that the RV has the correct remote panel wiring or harness available. This panel does not include the wiring harness. 3. Choose Mounting Location: Select an interior location that is accessible and suitable for the panel size and wiring route. 4. Use Template: Use the included instruction sheet and mounting template to mark the cutout and screw locations. 5. Connect Wiring: Connect the remote panel to the generator remote wiring according to the Onan instructions for the specific generator model. 6. Mount Panel: Secure the panel using the included mounting screws. 7. Test Operation: Confirm start/stop function and hourmeter operation before finalizing installation.
Package Contents: • Cummins Onan 300-4937 Deluxe Remote Panel • Illuminated start/stop rocker switch • Hourmeter • Mounting plate / panel assembly • Mounting screws • Instruction sheet with mounting template NOT Included — May Also Need: • Remote wiring harness • Fuse or fuse holder • Additional wire or connectors • Replacement generator-side wiring parts Confirm your RV’s existing remote panel wiring before ordering, especially if replacing a missing panel rather than a damaged one.
To confirm compatibility before ordering, have the following ready: • Generator model number • Spec letter • Serial number • Existing remote panel part number, if replacing one • Whether the generator is gasoline or LP vapor • Whether the generator has diagnostic capability Why this matters: Onan remote panels vary by generator series and control style. Matching the generator model/spec and wiring setup helps avoid ordering a panel that fits physically but does not function correctly with the generator.
Generator remote panels should be matched by generator model/spec and wiring configuration, not only by appearance.
If the generator operates correctly at the generator but not from the remote panel, inspect the panel, harness, connectors, and generator-side remote control circuit before replacing parts.
