I ended up mounting my brake controller on top of the tape deck for the center console. I used heavy duty velcro and it stays in place well, even when using the slide bar. I'm pretty happy where it's at. Maybe someone will do the same, so here's a pic of it.
I also found a nice way to mount the 7-pin trailer plug to keep it up and out of the way. Where it's at it won't collect a lot of the road salt and garbage from the roads, hopefully prolonging the life of it. I took out the right license plate lamp and to my surprise, the hole was almost large enough to fit the plug. I had to shave the body down slightly and then used clear window calk that is not supposed to freeze and be like 7 year or something of that nature. It's in there firm and it looks stock. The license plate still lit up alright with just one bulb, but just in case I changed it out for the sylvania led and its clearly visible now.
