This X AUTOHAUX trailer brake control switch panel restores factory-style trailer braking adjustment for compatible 2014–2019 Chevy Silverado and GMC Sierra trucks.

What does this trailer brake control switch do?

The switch controls the amount of electrical braking force sent to a trailer’s electric brakes so you can fine-tune stopping power for different trailer weights and road conditions. It provides a simple in-dash adjustment without needing an aftermarket brake controller mounted separately.

• Adjusts trailer braking intensity from the cab
• Works with factory vehicle wiring and dash location
• Maintains OEM look and ergonomics with a black finish

Is this panel compatible with my Chevy Silverado or GMC Sierra?

This panel fits specified model years and trims of the Chevrolet Silverado 1500 and 2500/3500HD plus GMC Sierra 1500 and 2500/3500HD listed in the product fitment. It requires vehicles equipped with electric trailer brakes and the factory 8-pin tow wiring connector.

• Compatible with 2014–2019 GMC Sierra and 2014–2018/2016–2018 Silverado trims listed

How is this installed and programmed?

Installation involves unplugging the old switch and plugging this unit into the factory 8-pin connector; trim and fasteners are reinstalled to restore the dash appearance.

• Verify 8-pin tow connector—this unit will not work with 4-pin connectors
• Truck must have electric brakes; no functionality without electric brake system
• Durable construction and OEM-style finish for reliable, long-term use
