5-Way Trailer Wiring Harness – 18 AWG Pure Copper, Heavy-Duty 5-Pin Flat Connector, Wishbone Style

Heavy-Duty 5-Way Trailer Wiring Harness

The Connective Solutions Group 5-Way Trailer Wiring Harness is designed to provide a reliable electrical connection for boat trailers, utility trailers, and other compatible towing applications. Featuring a durable 5-pin flat trailer-side connector and color-coded wiring, this harness is ideal for replacing worn or damaged trailer wiring or completing a new installation.

Available in 20 FT, 25 FT, 30 FT, and 35 FT lengths, allowing you to select the appropriate size for your trailer.

Premium Pure Copper Construction

Manufactured with 18 AWG, 100% pure copper wiring, our trailer harnesses are designed for reliable electrical conductivity and long-lasting performance. The stranded copper conductors provide flexibility for routing wiring along the trailer frame while maintaining dependable electrical connections.

High-quality PVC insulation helps protect the wires from everyday wear and exposure to demanding trailer environments.

Durable 5-Pin Flat Connector

The heavy-duty 5-way flat connector is designed to provide a secure connection to compatible towing vehicles. Its molded construction helps protect the connection and reduce wear during regular use.

The additional fifth circuit makes this harness suitable for trailer applications requiring an auxiliary electrical function, commonly used for reverse-lockout systems on compatible boat trailers.

Color-Coded Wishbone Wiring

The wishbone-style wiring configuration allows the harness to split at the trailer tongue and run along both sides of the trailer, making installation and wire routing more convenient.

Color-coded conductors help simplify identification and connection of the trailer's lighting and auxiliary circuits.

• Boat trailers

• Utility trailers
