Lippert Kwikee 25 Series Made in USA Lippert 365884 Pigtail Adapter for Kwikee 25 Series Entry Steps

When your automatic RV entry steps stop responding, a failed wiring connection is often the culprit. The Lippert 365884 pigtail adapter is the direct-replacement harness that bridges your Kwikee 25 Series step motor assembly to the control unit -- restoring automatic extend and retract operation every time the door opens or closes. At just 7.5 inches long with secure locking connectors and 16 AWG wire, it is a clean, cost-effective fix that does not require splicing or rewiring.

Restore Automatic Step Operation Without Cutting a Single Wire

The Kwikee 25 Series electric entry step is one of the most common OEM step systems on travel trailers, fifth wheels, and Class A and C motorhomes. Over time, the pigtail connector between the step motor and control box can crack, corrode, or pull apart -- especially when steps cycle thousands of times over years of use. This genuine Lippert replacement puts a fresh, factory-spec connector back in the circuit so your steps deploy reliably every single trip.

Because this is a plug-and-play adapter with matching male and female locking connectors, installation is straightforward: unplug the old connector, plug in the new one, and route the 7.5-inch harness neatly alongside the existing wiring. No crimping, no soldering, no guesswork.

Locking Connectors

Male and female ends snap and lock together, preventing vibration-induced disconnects on the road.

16 AWG Wire

Heavy enough for the step motor circuit load, with insulation rated for the under-step environment.

7.5-Inch Length

Matches OEM harness routing on Kwikee 25 Series steps -- no excess slack, no strain on connectors.

Made in USA

Manufactured to Lippert quality standards with a limited 1-year manufacturer warranty included.

What This Adapter Does in the System

The Kwikee 25 Series step control unit receives a door-switch signal and commands the step motor to extend or retract. The pigtail adapter is the short wiring bridge between the control unit output and the motor/step assembly connector. It carries the 12V DC switched circuit that drives step movement. A damaged or corroded pigtail in this position will cause steps to become unresponsive, to only partially deploy, or to stop mid-cycle.

Plug-and-Play Replacement: The 365884 uses the correct OEM connector bodies for the Kwikee 25 Series. No adapter fitting, no pin swapping, and no harness modification required on properly equipped Kwikee 25 Series installations.

Common Symptoms That Point to This Part

  • Steps do not extend when the door is opened
  • Steps do not retract when the door is closed
  • Step control unit powers on but sends no movement to the motor
  • Visible cracking, melting, or corrosion on the existing pigtail connector body
  • Intermittent step operation that gets worse in cold or wet weather

Installation Tips

  • Disconnect 12V power to the step system before replacing the pigtail -- pull the step fuse or disconnect the house battery.
  • Photograph the existing connector orientation before unplugging to confirm correct reassembly.
  • After plugging in the new pigtail, apply dielectric grease to the connector faces if operating in a high-moisture climate.
  • Restore power and cycle the door switch several times to confirm smooth extend and retract operation.
Compatibility Note: This pigtail is designed specifically for the Kwikee 25 Series entry step. Kwikee also produces 24, 26, and other series steps with different connector configurations. Verify your step series number -- typically labeled on the step motor housing or control unit -- before ordering.
Maintenance Tip: Inspect the step wiring harness and connectors annually, especially if your RV is stored outdoors. Rodent damage and UV degradation are leading causes of pigtail failure on steps that are otherwise mechanically sound.

Important Information
  • Always disconnect 12V power to the step system before handling wiring connectors. Even low-voltage DC circuits can cause sparks or damage control electronics if disconnected under load.
  • This part fits the Kwikee 25 Series ONLY. It is not a universal step harness. Installing on a different series step may result in connector mismatch or incorrect function.
  • Inspect the mating connector on the control unit for corrosion or damage before installing. A new pigtail connected to a corroded control unit port will not fully resolve the fault.
  • Do not operate entry steps with the vehicle in motion. Always retract steps before driving.
  • Weight capacity and step performance are determined by the step assembly itself, not this wiring adapter.
