I always recommend a Tekonsha Prodigy or P3, available on-line. I don't think they make a plug-in cable kit for your vehicle, but basically all you do is tap into a brake light circuit for the trigger, tap into battery power with a 10 gauge, 30 amp circuit with an auto-reset circuit breaker for main power, and run the output from the controller back to a plug you install on the rear bumper, again with a 10 gauge wire to carry the current. The plug will match the one on your trailer, usually a 6 conductor plug, and you add in the lighting circuits for brake lights and turn signals by tapping into those wires on the vehicle. We used to do this for all vehicles in the old days before they came pre-wired for trailers. Everything is available mail-order on line, just google Tekonsha to get started.
