GMC

T-Connectors and Plugin Connetors for GMC.  They have an O.E.M. compatible plug that attaches to existing connectors in the tow vehicles wiring harness.  This provides the easiest installation possible.  The T-connector for your vehicle provides everything required to complete a conventional trailer connection - the converter or power converter required for your vehicle is built into the T-connector.
