Vehicle-specific plug-and-play harness that connects to your Acura MDX's factory wiring behind the driver's-side taillight, providing a standard 4-way flat trailer connection with no cutting or splicing required.
Some automotive manufacturers install a special socket on the vehicle for vehicle-to-trailer wiring. A Curt T-connector like the 56192 utilizes that socket for simple, stress-free installation — rather than cutting, splicing, and soldering into your Acura MDX's wiring system, it uses OEM-compatible connectors to instantly provide a standard 4-way flat vehicle-to-trailer connection.
The included powered converter isolates the trailer load, giving you solid, reliable signal lighting without tapping into any factory circuits. Since it mounts behind trim panels near the rear lights, there's no need to route wires across the vehicle — the connection stays hidden and protected once installed. The kit includes the required fuses to activate the lighting circuit right away, along with a rubber dust cover for long-lasting weather resistance.
