Got my wireless installed today. This thing is GREAT! So easy to assemble in the tool box, on a workbench and not laying under a truck. Took my time and it still only took an hour at most.
Once built on the bench, I attached it to the top of my receiver hitch cross bar behind the rear bumper and tied power into the 7-pin trailer connector's hot and ground. Then T-fitting into the existing air bag lines and it was done. Maybe 20 minutes laying on my back to hook the stuff up.
