CURT 13146 Trailer Hitch & 56192 Wiring Harness - Towing

In this review of the CURT 13146 class 3 trailer hitch paired with the CURT 56192 vehicle-side 4-pin wiring harness, the bottom line is simple: this combo gives select Honda Pilot and Acura MDX owners a robust, vehicle-specific towing solution that covers both strength and electrical connection. The biggest reason to buy is the integrated fit and capacity - a 2-in receiver hitch rated up to 6,000 lbs gross trailer weight with a matching plug-in harness that provides a standard 4-pin connector while keeping the factory wiring intact. It is a practical, durable kit for owners who tow regularly.

Key Features

• Weight capacity: The hitch supports up to 6,000 lbs gross trailer weight and 900 lbs tongue weight, providing enough towing range for boats, campers and heavy cargo within the vehicle's towing limits.
• Vehicle-specific fit: Both the hitch and harness are designed for select Honda Pilot and Acura MDX models, which simplifies installation and avoids generic fit issues.
• 2-in receiver: The hitch uses a 2-in receiver tube to accept common accessories like a ball mount, cargo carrier or bike rack, increasing versatility for everyday hauling needs.
• Plug-in wiring: The CURT 56192 harness plugs into existing factory wiring to supply a standard 4-pin trailer connector without splicing, keeping the vehicle wiring intact.
• Durable finish and protection: The hitch features a dual-coat rust, chip and UV-resistant finish while the wiring harness includes a dust cover to protect the connector from the elements.
• Installation aids: The harness has an easy grip design with tabs for convenient connecting and disconnecting of trailer lights, reducing frustration during hookup.

Who It's For

This kit is best for Honda Pilot and Acura MDX owners who already have or intend to use their vehicle for towing boats, small travel trailers, cargo carriers or bicycles and want a tidy, factory-friendly electrical connection. It suits owners who value a vehicle-specific hitch that does not require major modification and who need the conventional 4-pin trailer wiring for older or basic trailers.

It is less suitable for buyers who need the highest possible tongue weight or who plan to tow trailers that exceed the stated 6,000 lbs capacity, or for those who require a multi-function or powered trailer connector beyond a standard 4-pin. Single-person installers should note the hitch is heavy and may require assistance during mounting.

Pros & Cons

Pros

• Strong 6,000 lb gross trailer weight capacity with a common 2-in receiver for broad accessory compatibility.
• Custom, vehicle-specific fit for select Honda Pilot and Acura MDX models simplifies installation and alignment.
• Wiring harness plugs into factory connectors to provide a standard 4-pin outlet and includes a dust cover for protection.
• Durable dual-coat finish on the hitch and easy-grip tabs on the harness enhance longevity and usability.

Cons

• The hitch is heavy, which can make single-person installation difficult and may require a second person or lift.
• The harness supplies a standard 4-pin connector only, so owners needing additional circuit functions must source a different harness or adapter.
