When your In-Wall slide-out loses communication between the controller and motor, a damaged or corroded wiring harness is often the cause. The Lippert 238992 is a genuine OEM-spec 6-pin replacement harness at 35 ft -- long enough for most full-size coach slide rooms -- with a protected wiring casing and pre-terminated male-to-female connectors for a direct plug-in swap. No splicing. No guesswork.
The Lippert In-Wall slide-out system -- commonly called the Schwintek system -- uses a dedicated wiring harness to carry 12V power and control signals from the wall-mounted controller board to the dual gear motors that drive the slide room. Over time, harness wires can chafe inside the wall cavity, connectors corrode from humidity, or the jacket cracks from repeated slide cycling. Replacing the harness with the correct-length OEM part restores full, reliable operation.
The 238992 is the 35 ft variant -- the longest in the Lippert harness lineup for this system -- and is the right choice for larger Class A motorhomes, fifth wheels, and travel trailers with extended wall runs between the control board and the slide motors. If your slide room is not responding, running only partially, or throwing controller faults, a harness swap is a logical diagnostic step before replacing motors or the control board itself.
Pre-terminated male-to-female 6-pin connectors match the In-Wall controller board and motor harness ports exactly -- no adapter needed.
Handles long wall-cavity runs in large fifth wheels and Class A coaches. Also available in 10, 15, 25, and 30 ft lengths if your run is shorter.
The outer jacket guards conductors against abrasion inside tight wall cavities and against moisture that builds up in slide room channels over time.
Cross-referenced by Forest River, Grand Design, Heartland, Jayco, Keystone, Thor, Winnebago, and Gulf Stream for wide coach compatibility.
The 238992 connects directly between the In-Wall controller (typically mounted inside the cabinet near the slide room) and the two slide motors. Male connector seats into the controller; female end terminates at the motor side. No cutting, splicing, or crimping required when replacing a like-for-like harness of the same length.
Lippert offers this harness in multiple lengths to match the wall-cavity run in different coach sizes and floorplans. Measure from the controller board location to the farthest motor before ordering. Using a harness that is too short will not reach; using one that is too long simply means the excess must be coiled and secured inside the wall cavity. The 35 ft version suits large-format coaches and long slide rooms where the controller is mounted far from the motor assembly.
The In-Wall (Schwintek) slide system is identifiable by its two slender gear motors mounted on vertical rails inside the slide-room wall, rather than the external rack-and-pinion or hydraulic systems used on other coaches. If your slide has this design and uses a Lippert In-Wall controller board, this harness is the correct replacement family. Check the label on your controller board for Lippert part confirmation.
