Oyviny 4-Pin RV Dinghy Towing Wiring Harness for Jeep Wrangler JK (2007–2018) — Pure Copper, Plug-and-Play

The Oyviny 58903 is a plug-and-play 4-pin RV dinghy towing wiring harness that lets 2007–2018 Jeep Wrangler JK models use RV tail, brake and turn signals while flat-towed.

If you plan to flat-tow a Jeep Wrangler JK (2007–2018, non–right-hand-drive) behind an RV, this wiring harness provides a simple, reversible way to route the RV’s signal feed into the Wrangler without cutting factory wiring. Built with pure copper conductors and heavy-duty ABS connectors, the kit connects to the vehicle’s lighting circuits and presents a standard 4-flat trailer plug at the front of the Jeep so the motorhome can control the Wrangler’s taillights, brake lights and turn signals.

How does this wiring harness let my Wrangler act like a trailer?

The harness ties the vehicle’s lighting circuits to a 4-flat trailer connector that mates to the RV’s socket, allowing the RV’s signals to control the Wrangler’s lights while flat-towed. No splicing into factory harnesses is required when installed correctly.

• Provides a standard 4-flat trailer plug at the vehicle’s front
• Routes RV brake, tail, and turn signals into the Wrangler
• Designed to avoid interference with factory lighting

What components come with the Oyviny 58903 kit and what are their roles?

The kit includes the main wiring harness, a 4-foot 4-way flat extension, a mounting bracket with hardware, and rubber dust covers for the connector. These parts keep the connector accessible and protected while making installation neat and secure.

• Main harness with pure copper wires and black protective loom
• 4' 4-way extension cable for reaching the RV’s socket
• Mounting bracket and screws to secure the flat plug in place
• Rubber dust cover(s) to keep connector ends clean when unused

How easy is installation and will it damage my Jeep’s wiring?

Installation is plug-and-play: connectors plug into factory-accessible points without cutting or splicing into the Jeep’s original wiring when matched to compatible models. The kit is intended to be reversible and not alter factory circuits when installed per instructions.

• Plug-in connectors reduce need for wire cutting or splicing
• Protective loom bundles wires and resists abrasion
• Includes mounting hardware to prevent loose cables

What materials and protections ensure long-term reliability?

Oyviny uses pure copper conductors for reliable electrical conductivity and heavy-duty ABS connectors to withstand repeated use. A black wire loom protects the conductors from wear, and rubber dust covers shield the connector from dirt and moisture when not in use.

• Pure copper wires for stable, low-resistance connections
• Durable ABS connector housings for mechanical strength
• Wire loom and dust covers to reduce wear and contamination
