Good To Know

Q: Does this harness work if my truck already has a factory 7 way plug? A: It is designed as a replacement or add-on trailer wiring kit, so check your existing connector style and harness routing before ordering. Many owners use it to restore a damaged plug or add a 4 way flat connection.

Q: Will I need extra adapters to tow different trailers? A: The kit includes both a 7 way blade and a 4 way flat plug, which covers most common trailer types without additional adapters. Trailers with specialty connectors may still need a separate adapter.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
