It is a bit involved mainly for the proper alignment. The main unit and the compressor which is a metal tube both fit nicely under the drivers seat. I thought it may not fit due to the seat tipping mechanism there for the new model but there was plenty of room. I had a problem with wire rub causing a broken, corroded power wire so be sure to route the wires where they can's rub and put in a flex conduit. I didn't install it myself but I did have to pull the wiring to re-route it so I got to see the system up close. The pull cable needs to be routed so it will not kink as the manual says. The tech support on the phone and by email was good. The tie in to the vacuum line looked simple. Overall I think I could have installed it myself but for me it would have taken most of the day but that's mainly because I'm not to flexible under the dash.
