When your RV slide-out switch stops responding or the wiring harness between your switch assembly and the slide controller shows wear, cracking, or a broken connector, this is the direct OEM replacement. Lippert part 178436 is a 6-inch wiring harness designed to reconnect your slide-out switch to the slide room control circuit -- restoring full in/out operation without cutting and splicing field wiring.
The wiring harness that bridges your slide-out wall switch to the slide controller sees repeated stress every time the slide moves -- flexing, vibrating, and occasionally being pinched against the slide room frame. Over time, the connector pins corrode, the insulation cracks, or the locking tab on the connector breaks, leaving the switch unresponsive even though the motor and controller are fine.
Lippert 178436 replaces that short 6-inch pigtail harness with an exact OEM-spec part -- correct connector housing, correct pin count, correct wire gauge -- so you get a plug-and-play repair rather than a wiring splice that can introduce new fault points.
Matches the factory Lippert connector housing and pin layout for direct plug-in replacement without cutting or splicing.
Designed for the standard switch-to-harness gap in Lippert slide switch assemblies -- no excess slack, no strain on connector seats.
Built to OEM wire gauge specifications to handle slide switch signal current without voltage drop at the controller input.
Disconnect the old harness at both ends, plug in the new one -- most installations require no tools beyond a flathead to release the connector latch.
In a Lippert slide-out system -- whether rack-and-pinion, hydraulic, or cable-driven -- the wall switch sends a directional signal (IN or OUT) to the main slide controller board. That signal travels through this short harness. If the harness connector is intermittent, the controller never receives a clean command and the slide will not move, or will move erratically only when you wiggle the switch.
Replacing the harness eliminates the connector as a variable before you start chasing controller or motor faults -- making it a smart first step in any slide troubleshooting sequence.
This harness is used across a wide range of Lippert slide-out configurations found in travel trailers, fifth wheels, and motorhomes from most major manufacturers. It mates with Lippert OEM slide switch assemblies that use the standard multi-pin harness connector. Confirm the connector style on your existing harness before ordering if you have an older or non-standard installation.
