You would need a seperate 7 way installed in your car as the brakes require a power wire to the battery. etrailer sells some simple kits where you plug in your 4 pole plug to the 7 pole plug and all you need to do is run a wire to the battery. They are quite easy to install. I would then recommend a prodigy wireless brake controller. They are pricey but its much more straight forward to use then wireing in a brake controller inside the car.
