I have rewired a number of Jeeps and have yet to use a kit. This is more because I'm a cheapskate than anything else. When you get the schematics, study them until you are comfortable with how the wires are run. One of the things I've done is adapt an existing loom from a donor rig. This allowed me to "clean up" an existing loom that has a fusebox already in it. The last one I used was off an early Bronco, however, most any of the simpler(IE early) looms will work. If you decide not to use an existing loom, then buy a couple old looms from a local U-pick yard. One of the looms should have a usable fusebox. Dismantle the looms and use the existing wires to replace the Jeep's loom. This will be much cheaper than buying a number of spools of wire and will provide you with color coding. While this method is somewhat labor intensive, it can usualy be done for well under one hundred dollars. More than that, the learning experience is priceless.
