Oyviny Brake Controller Wiring Adapter 4-Pin — Dodge/Jeep/Chrysler 2011–2021, Plug-and-Play

The Oyviny 3045-P is a plug-and-play 4-pin brake controller wiring adapter built to connect aftermarket brake controllers to Dodge Durango (2011–2021), Jeep Grand Cherokee (2011–2021) and Chrysler Pacifica (2017–2021) factory 7-way sockets without cutting or splicing.

If you're fitting an aftermarket brake controller to a compatible Dodge, Jeep, or Chrysler with the factory 7-way connector, this harness provides the correct 4-pin interface, reliable conductors and a pre-molded vehicle plug. It eliminates the guesswork of tracing wires under the dash and reduces installation time to a quick two-plug connection. The assembly is built for repeated use and exposure under dash conditions with protective sleeving and tin-plated terminals for steady conductivity.

How does this adapter simplify brake controller installation?

Instead of locating, cutting and splicing vehicle wires, you use the factory port under the dash where the 7-way tow connector is routed. The Oyviny harness plugs directly into that factory port and into the brake controller, making installation fast and reversible. No soldering or electrical expertise is required for a correct setup.

• Pre-molded vehicle connector fits factory 7-way port — no modifications needed
• Standard 4-pin brake controller plug accepted by most controllers
• Approximately 31 inches of cable for flexible positioning
• Quick plug-in connection preserves factory wiring integrity

Which brake controllers are compatible with the Oyviny 3045-P?

The adapter uses the common 4-pin brake controller format, so it works with many popular electronic controllers from major brands. Check your controller’s plug style; if it is the standard 4-pin flat trailer brake connector, it will mate with this harness. Compatibility covers both older and current Tekonsha, Draw-Tite and Reese models listed by the manufacturer.

• Tekonsha models: PowerTrac, Prodigy, P2, P3, Primus IQ, Voyager
• Draw-Tite Activator series (5100 / 5500 / 5520)
• Reese/RE ESE Towpower part numbers noted in product features
• Any brake controller using the standard 4-pin flat plug

What materials and construction features ensure durability?

The harness uses premium copper conductors and tin-plated terminals for reliable electrical contact and reduced corrosion over time. Wires are enclosed in a black nylon sleeve to protect against abrasion and incidental moisture beneath the dashboard. The molded plugs are made from ABS plastic for impact resistance and a stable fit into factory sockets.

• Pure copper wiring for consistent conductivity
• Tin-plated terminals to limit oxidation and ensure contact
• ABS plastic molded connectors for secure mating
• Nylon net tubing guards against wear from movement and vibration

Will this harness fit my specific vehicle and where do I connect it?

This harness is designed for Dodge Durango (2011–2021), Jeep Grand Cherokee (2011–2021) and Chrysler Pacifica (2017–2021) vehicles equipped with the factory 7-way trailer connector wiring. The custom-molded vehicle end plugs into the factory port usually located beneath the dash on the driver’s side; the other end plugs into your brake controller. Always verify model year compatibility before purchase.

• Fits listed model years with factory 7-way prewiring
• Vehicle end: custom connector matching factory port under dash
• Controller end: standard 4-pin flat brake controller plug
• Length allows mounting controller within comfortable reach of driver
