Answer to my own question after speaking to my dealer it that I must hard wire my brake controler in.
brake controllers aren't super difficult to install. Basically you need power, ground and then you need to tap the brake light wire under the dashboard somewhere. Then you need to run a line to the back of the truck for the brakes. Use big, heavy wire for the brakes, I found some out-door lighting wire that was very good for this application, it had a nice thick insulation jacket and was probably 8 or 10 gauge.
Make sure you get a GOOD controller. , not something off the shelf @ Walmart or autozone. I ran a Tekonsha Prodigy in two trucks until I bought my Ford PSD, which has the factory brake controller. You want one that is inertia based. It senses how hard you are applying the truck brakes and proportionally applies the trailer brakes. the cheap ones work like a light-switch, either brakes on or off. Obviously you don't brake like that and it makes driving a PITA.
