sixcow towing wiring harness for Jeep Wrangler JL & Gladiator 2018-2025 — 4-way 4-flat plug-and-play with dielectric grease

This sixcow Replace for Blue Ox EZ Light Wiring BX88368 is a plug-and-play 4-way towing wiring harness made to transfer turn, brake and tail light signals from a motorhome or tow vehicle to a 2018–2025 Jeep Wrangler JL and 2020–2025 Gladiator without splicing.

When you tow a Jeep JL or Gladiator behind an RV, you need a reliable way to relay lighting signals so the vehicle behind knows your intentions. The sixcow replacement for the Blue Ox BX88368 provides a custom-fit, T-connector design that attaches to the factory taillight sockets and routes a 4-flat harness to the hitch. The kit includes mounting hardware, zip ties and dielectric grease to help protect terminals from moisture and corrosion.

How does this harness fit my Jeep Wrangler JL or Gladiator?

The harness is engineered to mate directly with the factory wiring behind the taillights on 2018–2025 Wrangler JL models and 2020–2025 Gladiator trucks. No cutting or permanent splicing is required: the two T-connectors piggyback into the vehicle taillight sockets and the 4-flat cable is routed to the hitch area.

• Compatible with 2-door and 4-door Wrangler JL and Gladiator models listed for 2018–2025
• T-connectors plug into factory taillight harness without altering vehicle wiring
• 4-flat socket mounts near trailer hitch with included bracket
• Can be trimmed (saving white wire) for alternative pole adapters

What materials and protections does the kit use to resist corrosion and weather?

The assembly uses heavy-duty bonded wire and tin-plated copper terminals for improved conductivity and corrosion resistance. The 4-way socket has a tight-fitting rubber dust cover; the wiring and terminals are chemically resistant and designed to withstand outdoor exposure.

• Tin-plated copper terminals for consistent electrical contact
• Bonded wiring jacket for abrasion and chemical resistance
• Rubber dust cap to shield the 4-flat connector from moisture and debris
• Includes dielectric grease to help preserve terminal integrity

How easy is installation and what comes in the box?

Installation is straightforward and typically finished within 15 minutes using the included hardware and instructions. No vehicle wiring modifications are needed: mount the converter, attach the two T-connectors to the taillight sockets, route the 4-flat to the hitch, and secure the bracket and cables.

• EZ plug-and-play design — no cutting, splicing, or vehicle rewiring
• Includes mounting bracket, zip ties, and installation hardware
• Clear installation manual and dielectric grease included
• Can be quickly removed or transferred between towed vehicles

Will this kit transmit all required lighting signals while towing?

Yes — the harness transfers left and right turn signals, brake lights and tail lamps from an RV or tow vehicle to the towed Jeep. That ensures compliance with towing lighting requirements and makes your vehicle’s movements clear to drivers behind you.

• Transfers left turn, right turn, brake, and tail lamp signals
• Designed for safe, visible signaling when flat-towing behind an RV
• Works with factory lighting circuits without altering vehicle electronics
• Bracketed 4-flat connector keeps the socket accessible at the hitch
