Oyviny Brake Control Wiring Adapter 3064-P for 2019–2024 GMC Sierra & Chevy Silverado — 4‑Pin Plug, 31" Harness

The Oyviny 3064-P Brake Control Wiring Adapter is a plug-and-play harness that connects an aftermarket 4-pin electronic brake controller to 2019–2024 GM trucks and SUVs without cutting or splicing.

If you tow with a 2019–2024 GMC Sierra, Chevrolet Silverado 1500/2500/3500, Chevrolet Tahoe, Chevrolet Suburban, or GMC Yukon that has the factory tow package, this adapter lets you install a compatible brake controller quickly and cleanly. The harness uses a standard 4-pin connector, 31 inches of protected wiring, and OEM-style terminals to preserve vehicle wiring integrity while enabling electric trailer brake control.

What vehicles and brake controllers work with this harness?

The Oyviny 3064-P is built to mate with GM models from 2019 through 2024 equipped with the factory tow package. It accepts common 4-pin brake controller plugs used by many leading brands, making it straightforward to add aftermarket brake control electronics.

• Compatible vehicles: GMC Sierra, Chevrolet Silverado 1500/2500/3500, Suburban, Tahoe, Yukon (2019–2024; factory tow package required).
• Compatible controllers include: Draw-Tite Activator I/II/III, Tekonsha PowerTrac/Prodigy/P2/P3/Primus IQ/Voyager, REESE Towpower models listed.
• Note: Not compatible with CURT brake controller models.

How does installation work and how long does it take?

Installation is plug-and-play with no cutting, splicing, or modification of the vehicle wiring—simply plug the adapter into your new brake controller and insert the factory-style connector under the dash. Typical installation time is under 30 minutes for someone familiar with dashboard wiring access.

• Plug the 4-pin connector into the controller, then plug the custom OEM connector into the dash port.
• 31-inch cable length gives room to position the controller without stretching wires.
• No trimming or tapping into the vehicle harness, so factory wiring remains intact.

What materials and construction features improve durability?

The harness combines ABS plastic housings, pure copper conductors, and tin-plated copper terminals to maintain electrical conductivity and resist corrosion. A protective black nylon braided sleeve shields the cable from abrasion and road exposure, extending service life in towing environments.

• Copper wiring and tin-plated terminals for reliable electrical performance.
• ABS connector bodies resist impact and heat under the dash.
• Nylon braided sleeve defends against wear, moisture, and chafing along routing paths.

Will this harness affect vehicle warranty or diagnostics?

Because the adapter uses the factory-equipped diagnostic connector under the dash and does not alter factory wiring, it minimizes risk to vehicle electronics and preserves factory wiring. Still, check your vehicle warranty terms or dealer guidance if concerned about aftermarket accessory installation.

• No cutting or splicing—vehicle harness remains unmodified.
• Reversible: remove the adapter to return the vehicle to stock condition.
• Recommended to confirm with dealer if you have specific warranty questions.

Who is this for: The Oyviny 3064-P harness is ideal for owners of 2019–2024 GM trucks and SUVs with the factory tow package who want a clean, OEM-style way to add a compatible 4-pin electric brake controller. It suits DIY installers and professional shops looking to avoid splicing while keeping wiring tidy and durable. If you plan to use a CURT controller, choose a model-specific solution instead; otherwise this harness provides a reliable bridge between popular controllers and GM factory wiring.
