The CURT 56046 is a vehicle-side T-connector that adds a 4-way flat trailer socket to select 2006–2013 Chevrolet Impala models. It plugs into the factory taillight connectors, so there is no cutting, splicing or soldering. That plug-and-play design is its main advantage over universal splice-in harnesses, which cost less but take longer and can void wiring. It suits Impala owners who tow a small utility trailer, boat or camper and want a clean, removable install.

Owners of the Impala generally report a straightforward plug-in install that works with small trailers. Complaints center on fitment confusion across trims and the limited 4-way output.
This is a vehicle-specific custom wiring harness, also called a T-connector, for select 2006-2013 Chevrolet Impala Limited models. It plugs into the vehicle's electrical system and provides a standard 4-way flat trailer wiring socket. It is meant for vehicles that do not already have wiring for towing a trailer.
The harness uses OEM-compatible connectors that plug into the taillight assembly. This plug-and-play design means no cutting, splicing or soldering during installation. It includes the wiring components needed to make the trailer connection, plus a dust cover that keeps the connector clean when not in use.
The 4-way flat connection covers the tail lights, brake lights and turn signals. The harness is made in the USA and has a limited one-year warranty.
