Youtube has a video install on this, which has good basic info, but if you live in the northern states I would avoid routing the power wire on the outside. I recommend routing under the plastic on the inside of Jeep. Firewall routing, as recommended, is a pita. Use the opening on the drivers side to run the battery wire. Be prepared to extend the wire, for me, it wasn't long enough to reach the battery, but much easier than moving the fuse control box and trying to poke a hole in the grommet (hard to get to) on the passenger side. Works great and good quality.
