Just upgraded to a rig that has an integrated brake controller so I don't need this anymore. If you are towing and don't have one it's well worth the upgrade. I used this to pull my 6x12 enclosed trailer with a mid-sized SUV. Really took the load off my SUV and made for a safer transport. $75 shipped or pick up/delivery to NJMP. Includes what is shown. I misplaced the install guide when cleaning out the old car, but it's available online from Tekonsha.
