The Jordon's mechanical portion is only the cable that attaches to the brake pedal. It attaches very easy to the clamp and housing porvided and that part is hooked up by tightening 2 set screws.
When the brakes are applied the cable is pulled and how much pull will determine how much the unit applies brakes to the trailer. There is also a sensitivity set on the Jordon so you can make the brakes more or less sensitive. Very simple really.
I really wouldn't want to get into brake surgery as you have put it myself, but I think the brakesmart is a good system. However, if I were to purchase one I would de3finately have it installed by a professional. Don't like the idea of something going wrong (Hate Mr. Murphy) and suddenly having no brakes.
If it's electronics that you like then the choice should be the Prodigy without question. IMHO It is far far ahead of the others of the same catagory.
