Keep your RV slide room operating reliably with this OEM-style 12-inch wiring harness from Lippert Components. Designed to connect the slide-out switch to the slide room control board, part 117428 is a direct replacement for worn, damaged, or corroded harness wiring in a wide range of Lippert-equipped travel trailers and fifth wheels.
Slide-out wiring harnesses take a beating over time -- flexing repeatedly as the room extends and retracts, exposed to heat, moisture, and road vibration. When a harness fails, the slide switch loses communication with the control module and the room stops responding. Replacing the harness with the correct OEM Lippert part is the fastest path back to a working slide.
Lippert part 117428 is a 12-inch harness assembly built to factory specifications for Lippert slide room systems. The 12-inch length is sized for the typical routing distance between the wall-mounted switch and the slide control board in standard coach wiring bays. Using the correct length avoids stress on connectors and eliminates makeshift splicing.
Factory part number 117428 -- an exact replacement designed by the same manufacturer that built your slide system.
Pre-measured 12-inch harness for the typical switch-to-board routing distance in Lippert slide room installations.
Mates directly to Lippert slide switch and control board connectors -- no splicing or pin-out changes required.
Replace just the failed harness rather than the entire switch assembly, saving time and cost on a common slide room issue.
If your Lippert slide room behaves erratically or stops responding to switch inputs, the switch harness is one of the first components to inspect. Look for these signs:
Replacing the slide switch harness is a straightforward task for anyone comfortable with basic RV electrical work. Disconnect shore power or turn off the battery disconnect before beginning. Locate the slide switch wiring bay (typically behind the interior switch panel or within the slide control compartment), unplug the existing harness from both the switch and the control board, and plug in the new 117428 harness in its place. Secure any slack with existing cable management clips.
Lippert Components is the dominant OEM supplier of slide-out mechanisms in the North American RV industry, found in coaches from Forest River, Keystone, Coachmen, Grand Design, Heartland, and dozens of other manufacturers. Their electric slide systems use a standardized control architecture -- a wall switch, a dedicated harness, a control board, and a 12V DC motor -- making individual component replacement practical without swapping the entire mechanism.
