It comes with everything, the 4 pin connector, the mount for under the bumper, and the bundle that goes up in the kick panel. Had to upgrade to a 7 pin for bigger trailers & brakes. It is used & has been under my truck
$25 shipped, or up for trade. Nothing in mind really, kind of wanting a pocket holster for my S&W j frame, or if you have something of equal value or something + cash do tell.
