Genuine Lippert replacement wiring harness for In-Wall (Schwintek) slide-out systems. This 5 ft, 6-pin male-to-female harness restores the critical controller-to-motor connection with a protected wiring casing and OEM-spec connectors -- no splicing, no improvising.
The Lippert In-Wall slide-out system -- often called the Schwintek system -- uses a dedicated 6-pin wiring harness to carry control signals and motor power between the slide-out controller and the rack-and-pinion drive motors. When this harness fails due to chafing, connector corrosion, or pinch damage, the slide room may stop responding entirely or behave erratically. Part number 238744 is the genuine Lippert replacement for the 5 ft run.
This harness uses a male connector at one end and a female connector at the other, matching the OEM layout exactly. The protected outer casing shields the conductors from abrasion and moisture -- important in the tight, high-movement spaces where In-Wall slide-out wiring lives. No terminal crimping or pin extraction is needed; simply unplug the old harness and plug in the new one.
Male-to-female configuration matches factory In-Wall system wiring without modification.
Sized for standard slide-out controller-to-motor runs. Also available in 10, 15, 25, and 30 ft lengths.
Sheathed wiring resists abrasion and moisture in tight underbody and wall cavities.

Lippert's In-Wall slide-out system is one of the most widely used slide mechanisms in the RV industry, found across travel trailers, fifth wheels, and motorhomes from virtually every major manufacturer. The system uses two small geared motors mounted inside the slide-out wall cavity, driving a rack-and-pinion gear track to extend and retract the room. The controller communicates with both motors simultaneously through the 6-pin harness to keep the room from racking (twisting unevenly).
Because the harness routes through moving wall sections, it is subject to fatigue, pinching, and connector wear over years of cycling. A damaged harness is one of the most common causes of In-Wall slide-out failure and is one of the least expensive fixes -- provided you use the correct replacement length and connector configuration.
No splicing or rewiring required. The 238744 uses factory-matched connectors for a direct swap. Disconnect the old harness at both ends, route the new one through the same path, and reconnect. Verify slide operation before buttoning up wall panels.
The 5 ft harness (238744) covers most standard controller-to-motor runs. If your existing harness is longer than 5 ft -- measure before ordering -- Lippert also offers this harness in 10 ft, 15 ft, 25 ft, and 30 ft versions. Using a harness that is too short and stretching it can cause connector stress and intermittent faults. Always match or slightly exceed the original length.
This Lippert part is cross-referenced as a service part by: Forest River, Grand Design, Heartland, Jayco, Keystone, Thor Industries, Winnebago, and Gulf Stream. If your RV uses the In-Wall (Schwintek) slide-out system, this is the correct harness regardless of brand -- confirm by matching the 6-pin connector style and harness length.
