CURT 4-Pin Vehicle-Side Custom Trailer Wiring Harness, Fits Select Chevrolet, GMC C/K, Blazer, Suburban

If your vehicle lacks wiring for towing a trailer, CURT custom wiring serves as the ideal solution.

A custom wiring harness, also known as a T-connector, is a plug-and-play electrical device that connects to your automotive electric system and provides a standard, universal trailer wiring connection.

This is achieved using two or more vehicle-specific, OEM-compatible connectors that plug into the taillight assembly, eliminating the need for cutting, splicing, and soldering during installation.

Custom wiring harnesses are vehicle-specific, and while they are not available for all vehicles, they offer one of the fastest, easiest, and most secure methods to wire a vehicle for towing.

This particular plug-in harness provides a 4-way flat connector socket and is designed as a custom wiring harness to fit certain years of the Chevy Blazer, K5 Blazer, C10, C20, C30, K10, K20, and K30 pickup or Suburban and GMC C15, C1500, C25, C2500, C35, C3500, K15, K1500, K25, K2500, K35, and K3500 pickup or Suburban (to verify your vehicle compatibility, see application info).

It includes all necessary wiring components to establish a reliable trailer wiring connection and features a dust cover to keep the connector clean when not in use.
