FBULWSEC RV Stabilizer Jack Switch Replacement 2-Pack — IP66 Waterproof, Pre-Wired for Lippert High-Speed Jacks

FBULWSEC 387874 is a direct-replacement electric stabilizer jack switch and harness (2-pack) built to work with Lippert high-speed power stabilizer jacks and resist water and dust with an IP66 rating.

If a worn switch or frayed wiring leaves your RV or fifth wheel stabilizer jacks unreliable, this FBULWSEC 387874 replacement gives you a like-for-like control unit that restores extend/retract operation. Designed to match common Lippert part footprints and wiring styles, it replaces switches such as LC298707, LC198641 and LC363284 without modification in most installations. The pair of switches includes clearly labeled EXTEND and RETRACT markings and pre-terminated wires with metal contacts to simplify reconnection to your trailer harness.

How will this replacement switch restore my RV’s stabilizer jack function?

The 387874 switch replicates the original motor control interface used on Lippert high-speed stabilizer jacks, allowing your jack motor to receive extend and retract commands again. It supplies the same terminal layout and pre-crimped contacts so you can reconnect quickly and accurately.

• Direct fit for common Lippert jack models (e.g., LC298707, LC198641, LC363284).
• Pre-wired with metal contacts for fast plug-in or crimp installation.
• Clearly marked EXTEND / RETRACT legends to avoid wiring mistakes.

Is the switch durable enough for outdoor use and camping conditions?

This switch is engineered for outdoor automotive environments: the housing and internal connection surfaces are treated for improved corrosion resistance, and the sealed design keeps out dust and splashing water. The IP66 rating confirms protection against powerful water jets and complete dust ingress, making it suitable for typical road and campsite exposure.

• IP66-rated waterproof and weatherproof enclosure.
• Improved circuit connection and surface finishing for longevity.
• Sealed construction protects internal parts from moisture and dirt.

What does installation look like — can I swap it myself?

Installation is straightforward for someone comfortable with basic RV electrical work: disconnect battery power, remove the old switch from the rear landing gear leg, match wire colors or terminals, and attach the pre-crimped metal contacts to the vehicle’s harness. Because it’s offered as a two-pack, you’ll have a spare or a second unit ready for another leg if needed.

• Simple removal of existing switch and wiring reconnection required.
• Pre-crimped metal contacts speed up reconnection and reduce error risk.
• Two-pack provides immediate replacement plus a backup unit.

Will this switch work with different stabilizer jack configurations?

The 387874 is made to fit many high-speed Lippert stabilizers and is compatible when the original switch shares the same terminal style and function. Verify your current switch part number or physical terminal layout before ordering; the product is meant as a like-for-like swap, not a universal rewire solution.

• Compatible with multiple Lippert part numbers and high-speed jack designs.
• Best used as a direct replacement matching existing terminal layout.
• Not intended for custom control conversions without electrical adjustments.

Who is this for? Installers, RV owners and maintenance technicians who need a reliable, weatherproof replacement switch for Lippert high-speed stabilizer jacks will find the FBULWSEC 387874 useful. It suits DIYers comfortable with basic electrical reconnections and service shops that want a practical two-pack spare. Choose this replacement when you need clear extend/retract labeling, pre-terminated wiring for faster swap-out, and a sealed unit designed to withstand road and campsite conditions.
