What is it going under?Did you get it new? There should be instructions for a new set-up,maybe not model specific,but something to get you in the ball park.Assure that all th ebrackets are there and the mounting hardware.Find a nice spot under hood or in the trunk for the compressor. Your adjustment valve should be routed to the interior of your ride so that you have ready access to it. Route and secure all air lines to the frame,keep all slack out of them to avoid catching them on anything.Any place where they may make contact with adjoing frame braces they should be routed over and not layed directley across them as to prevent chaffing of the lines.
