So far so good
Could have had better instructions but I was able to figure out a cleaner install by hooking to my brake pressure application gauge on the dash instead of the lines off the treadle valve. Eliminating the need of the check valve which I was able to return.

Can't figure out how to Install.
The Directions are so vague and not vehicle specific. It only comes with mounting hard ware, Still can't find where to patch into air lines, What valve I need to attach air line to unit, or where to find a two way check valve as per instruction . I'm totally lost on this product.

Should come with hardware and better instructions.
Once you get this you’ll be off to the parts stores trying to track down fittings to connect the air line. Why they don’t include some fittings is beyond me. Instructions look to resemble some notes written on a napkin.
