Plug-In Brake Controller Harness for Ford Trucks

This CARROFIX wiring adapter connects an electric brake controller to the factory port beneath the dashboard on compatible Ford and Lincoln vehicles. The pre-wired OEM connector and standard four-flat plug allow a direct plug-and-play installation without cutting or splicing factory wiring. A nylon mesh sleeve protects the harness from abrasion for long-term durability.

Suits owners adding trailer brakes to listed Ford

Drivers of 2009-2021 F-150, 2017-2022 F-250 350 450 550 Super Duty, 2015-2022 Expedition and 2015-2022 Lincoln Navigator can install a brake controller quickly. Vehicles outside these model years or without the factory brake-controller port cannot use this harness.

Buffer type 43400 defines the internal circuit

The harness is built around a buffer 43400 design with tin-plated copper terminals for stable conductivity. This specification determines electrical compatibility with the vehicle's braking system, so verify that your controller requires this buffer type before purchase.
