This Lippert harness carries the control signal from the slide-out controller to the motor on in-wall slide systems, replacing a damaged or corroded 30-foot run. It uses the same 6-pin male-to-female connection as the original Lippert wiring, so it's a straightforward swap rather than a full rewire.
Confirm your slide-out uses Lippert's 6-pin in-wall harness setup before ordering, since connector types vary across slide mechanisms.
