Add reliable trailer lighting capability to your 2010-2013 Chevrolet Equinox or GMC Terrain without cutting a single wire. The CURT 56094 T-One connector taps directly into your vehicle's existing tail light harness and delivers a clean, weather-resistant 4-pin flat output ready for your trailer, bike rack, or cargo carrier.
The CURT 56094 is a vehicle-specific T-One connector engineered for the 2010, 2011, 2012, and 2013 Chevrolet Equinox and GMC Terrain. Unlike universal splice-in kits that require cutting into your factory wiring, the 56094 uses a plug-and-play T-harness design -- your factory connectors unplug, the CURT harness goes in the middle, and you're done. No splicing, no taping, no guesswork.
This is part of CURT's T-Connector (T-One) family, which covers thousands of vehicle-specific applications. The 56094 slots in at the rear of the vehicle near the tail light assemblies and terminates in the industry-standard 4-pin flat connector that works with the vast majority of trailers, bike racks, cargo carriers, and small utility trailers on the road today.
Plugs directly into the factory tail light connectors. Factory wiring is never cut or modified, keeping your vehicle's electrical system intact.
Engineered exclusively for 2010-2013 Chevrolet Equinox and GMC Terrain. Connectors and lead lengths match the factory harness routing exactly.
Outputs the universal 4-pin flat connector -- compatible with the vast majority of trailers, bike racks, and cargo carriers sold in North America.
Built-in converter handles LED-to-incandescent and separate-to-combined brake/turn signal conversion as needed by the vehicle's lighting system.
Modern vehicles like the Equinox and Terrain use sophisticated body control modules (BCMs) and computer-managed lighting systems. Splicing directly into these circuits can trigger fault codes, illuminate warning lights, or cause erratic trailer light behavior. CURT's T-One design avoids all of that -- the harness sits between the factory plugs, drawing signal safely without loading the BCM outputs beyond spec.
Many Equinox and Terrain owners also use this harness to power 4-pin flat accessories beyond traditional trailers: rear-mounted bike racks with integrated lighting, fold-out cargo carriers with running lights, and small pop-up camper trailers all use the same 4-pin flat standard.
The 4-pin flat output carries all four standard trailer lighting functions:
Note: This harness does not include a 12V auxiliary (Blue) or electric brake output (Black). For trailers requiring electric brakes, a separate brake controller and 7-pin wiring will be needed.
Most owners complete this installation in 15 to 30 minutes with no special tools. The general process for the Equinox and Terrain:
The CURT 56094 wiring harness is designed to pair with trailer hitches rated for the 2010-2013 Equinox and Terrain platform. CURT offers several hitch options for these vehicles (including CURT part numbers in the 11000-series) that use the same receiver receiver opening. The 4-pin flat connector on this harness is the correct electrical interface for all of those applications.
