Review on Tekonsha 7686 Prodigy Control Mounting by Roger Diaz

If you shorten the back of the case a bit it works fine with the P3 controller. I used a dremel to sand down about 1/8" of the back of the case to allow the harness connector to connect to the controller as the existing hole would otherwise partially cover it. It is currently attached to my F-150 with velcro direct attached under and to the right of my steering wheel, but I have to use a different velcro as velcro is stronger than velcro; I end up peeling the velcro from the surface it's on instead of peeling the velcros off, although I did the mounting surface with 91 % isopropyl cleaning prepared.
