I used one to wire a swb buggy a few years ago it's pretty basic and you need to be able to break down a wiring diagram but really it worked well. Plan on adding to it. Change the fuse box for a decent blade type. You will need extra connectors, and tape. Do you have a good quality soldering iron? And buy some heat shrink tube combinations.
If you plan a neat and well laid wiring hook up it will work but isn't a one stop kit. You will need more wiring.
