Wire your trailer with this universal, splice-in wiring harness so that you can connect the trailer's wiring to your vehicle's during towing. Wishbone design removes need for a jumper wire between tail lights.

This 18" long adapter plugs in to your 7-way, RV-style, vehicle-end connector to convert it for use with a 4-way or 5-way flat connector on your towed vehicle or trailer.

This 4-wire flat, trailer-end connector includes a 4' long, jacketed cable with stripped, color-coded wires for easy installation.
