CURT 4-Way Flat Trailer Wiring Harness for Select Honda/Acura/Isuzu — Vehicle-Side Plug-and-Play with Dust Cap

CURT 55336 is a vehicle-specific, plug-in 4-way flat trailer wiring harness that installs without cutting or splicing to provide a reliable connection for tail, turn and brake lights.

This custom CURT T-connector is engineered to match the factory electrical interface on select Honda, Acura and Isuzu models, delivering a universal 4-way flat socket for towing. Designed for a simple plug-and-play hookup, the harness uses OEM-compatible plugs and includes all necessary installation hardware plus a dust cap to protect the socket when not in use. Built with SMT circuitry and a tail light converter, the unit helps ensure proper signal translation between the vehicle and trailer lighting systems.

Which vehicles does this CURT wiring harness fit?

The CURT 55336 is made to fit specific model years and trims of Honda, Acura and Isuzu vehicles—commonly Accord, CR-V, Element, Odyssey, Pilot and Prelude, Acura Integra, CL, RL, TL and MDX, and the Isuzu Oasis. Confirm compatibility with your exact year and trim using the product application guide before purchase. Installation requires the matched OEM connector location to be present on your vehicle.

• Fits select Honda, Acura and Isuzu models (verify application list).
• Designed for vehicles with the factory wiring socket already installed.
• No vehicle-specific splicing required when the OEM connector exists.
• Includes dust cover and mounting hardware for secure installation.

How does the plug-and-play design simplify installation?

This CURT custom connector plugs directly into the vehicle’s factory socket so you don’t have to cut factory wires or splice new connections. The assembly arrives ready to connect and typically mounts near the rear bumper area for quick access. If your vehicle has the OEM socket, installation usually takes minutes rather than hours and avoids permanent changes to the vehicle harness.

• Uses an OEM-compatible plug—no cutting or soldering required.
• Mounting hardware included for a tidy, secure fitment.
• Dust cover protects the connection from dirt and moisture.
• Plug location mirrors factory access points for easy reach.

What electrical features ensure dependable trailer lighting?

The harness provides a standard 4-way flat output that carries tail, brake and turn signals to a trailer. It integrates a tail light converter and SMT (surface-mount technology) circuitry to translate vehicle signals correctly and improve long-term durability. CURT tests each custom connector to verify functionality before it ships.

• 4-way flat socket delivers brake, turn and running lights.
• Tail light converter ensures correct signal compatibility.
• SMT circuitry for consistent performance and extended life.
• Factory-matched plug reduces risk of wiring faults during installation.

What comes in the box and how is it protected?

The package contains the vehicle-side connector assembly, mounting hardware and a protective dust cap for the trailer socket. Hardware lets you fasten the socket near the bumper or in the factory mounting location for a secure, OEM-like finish. The dust cover helps keep the contacts clean when the connector isn’t in use.

• Complete vehicle-side wiring assembly with OEM-style plug.
• Mounting screws, clips or brackets as required for installation.
• Protective dust cap to prevent corrosion and debris build-up.
• Packaging validated to protect components during shipping.

Who is this for: Drivers who own one of the supported Honda, Acura or Isuzu models and want a clean, reversible trailer electrical connection without modifying factory wiring. It’s ideal for occasional or regular tow vehicle owners who prefer OEM-style installation, upfitters seeking a reliable plug-in solution, and anyone who wants a compact, protected 4-way trailer socket installed professionally or DIY.
