First, if I could give it 6 stars, I would. Before the nitty gritty details get fleshed out, you will love this compressor.Set up: it is very important to spend time to choose a location in/on your vehicle that is cool and within your skill set. If you choose the rear of your vehicle you will need large Guage battery wire to add onto the supplied wire (which is more than long enough for installation in the engine bay). If you choose to run the switch into your dash you will need to prepare, find two connections (an ignition source and power source). This means you need to have adequate skills to run wires through the firewall, find and splice wires, and cut an opening to mount the switch. Do yourself a favor: be prepared with a plan before you begin installation.Connections: I chose to keep the switch and all components in the engine bay, as seen in the picture. That said, Jeeps have gigantic engine bays. I used a fuse "add a circuit". It cost $10 at Autozone and it took about 3 minutes to connect. I would recommend the same approach if you choose to install into the dash, it is that easy. Mechanical connections; it comes with all you need to set up but you will to buy the specific pieces you need for your setup (again, PLAN ahead).Use: I have 31" tires. It took me longer to let air out than the compressor did to inflate them. I aired down to 10psi then inflated to 45psi, it was done in about 10 minutes. Get yourself a Guage pressure tool and you will cut at least 1 minute off. In that ten minutes the compressor reached a few hundred degrees ( I know because I accidently touched it, big dummy). So, again, find a cool and open location.I am seriously amazed. The finished installation runs around $300, depending on your custom setup. For an inexpensive option this tool is well built and performs it's given function quite well. I want one for each of my other vehicles. Buy it, NOW.
