Oyviny 3035-P Brake Controller Wiring Adapter Compatible

The Oyviny 3035-P is a plug-and-play 4-pin brake controller wiring adapter designed to connect aftermarket brake controllers to compatible Ford, Land Rover, Lincoln and Mercury vehicles without cutting or splicing.

If you need a reliable harness to install an electric brake controller, this pre-wired adapter simplifies the job by mating directly with the factory dash connector. Built with tin-plated copper terminals, ABS housings and a protective nylon sleeve, the 31-inch cable minimizes wiring errors and lets you position the controller where it’s most convenient. It works with many popular controllers from Tekonsha, Draw-Tite and Reese/Towpower and covers a broad range of models from the mid-1990s through recent years — but always verify vehicle compatibility before ordering.

Which vehicles and controllers does this adapter support?

This harness was created to fit a long list of Ford family vehicles, several Land Rover and Range Rover models, plus Lincoln and Mercury vehicles across specified year ranges. It uses the industry-standard 4-pin brake controller plug so it’s compatible with many common aftermarket controllers.

• Ford: F-150 (1994–2008), F-250/F-350 (select 1994–1996), F-450/F-550 (selected years), Bronco, Excursion, Expedition, Explorer, Flex, Windstar and more.
• Land Rover/Range Rover: LR3, LR4 and Range Rover models noted in product fitment (2005–2022 ranges).
• Lincoln/Mercury: Navigator, Aviator, Mark LT, MKT and other compatible years.
• Compatible controllers: Tekonsha P2/P3/Primus/Prodigy, Draw-Tite Activator series, Reese/Towpower models listed.

How simple is installation and what tools are required?

Installation is straightforward: plug the adapter into the brake controller, then plug the factory-style connector into the dash port — no wire cutting or splicing. That makes it suitable for DIY installation in most cases and reduces the risk of wiring mistakes.

• No crimping, soldering or cutting required for compatible vehicles.
• 31-inch cable length allows flexible controller placement under the dash.
• Standard 4-pin connector aligns with most aftermarket controllers for a quick connection.
• Basic tools only if you need to access the dash panel (screwdriver or trim tool).

What are the build quality and durability features?

Oyviny constructed this adapter with long-term service in mind: ABS plastic housings protect the plug bodies while tin-plated copper terminals provide consistent conductivity. The black nylon net tube shields the cable from abrasion and routing damage under the dash or behind panels.

• ABS plug housings resist cracking and keep pins aligned.
• Tin-plated copper terminals improve corrosion resistance and conductivity.
• Nylon net sleeve protects cable from chafing and heat exposure.
• Pre-terminated ends reduce potential short circuits and wiring errors.

Will this adapter change how my brake controller works?

The adapter only provides a correct, factory-style electrical interface between your vehicle and the aftermarket controller; it does not alter controller logic or braking behavior. Use it to ensure a clean signal path and proper connector fit so your chosen controller can perform as designed.

• Maintains original signal routing to the trailer brake circuit.
• Does not add electronic functions or modify controller settings.
• Supports standard 4-pin brake controller wiring conventions.
• Helps avoid miswiring that could affect controller performance.

Who is this for: The Oyviny 3035-P wiring adapter is for drivers who want a clean, reliable way to install an aftermarket 4-pin brake controller in compatible Ford, Land Rover, Lincoln or Mercury vehicles without cutting factory wiring. It’s a good choice for DIY installers, fleet technicians and anyone replacing a damaged factory connector who prefers a plug-and-play solution. Always confirm your vehicle year and dash connector match the listed fitment before purchase.
