Curt Brake Control Wiring Guide

Many pickups and SUV's with a towing package have the necessary wires preinstalled in order to quickly and easlily install a brake controller for your trailer. Use this guide to find out if there is a plug in adapter for your vehicle. If not, you will need either to hard wire your brake controller or install a universal kit.
