The kits are pretty easy to install as long as you can jack your car off the ground (or have lots of clearance) and you don’t mind being on your back for a long time. Back at the shop, we usually budgeted about 2 hours for install, so if it’s a first time, you may want half a day on the weekend or something. The kits come with mounting hardware and a controller/transformer unit.
Typically, you’ll just need a drill for making screw holes (unless the kits has self-tapping ones), a screw driver, wire stripper/cutter, electrical tape or connectors (just in case).
Basic principal is that the individual tubes will either hook one into another and then lastly to the controller, or they will all hook individually to the controller. Either way, after mounting, it’s just running tons of wire all over the place. The longest part is trying to ‘tuck’ them so it doesn’t look like crap under there.
Good luck!
