We have used American Autowire almost exclusively for the last 20+ years. High quality, excellent diagrams/instructions and tech support if needed. In addition they are one of the few that discuss proper crimping methods. I also like the fact that you can cut the wires to length and terminate at the fuse box using only what you need circuit wise. A lot of the kits are pre wired at the fuse box leaving a balled up mess or wires to cut off.

BTW: Due to downsizing, I do have an extra set of the Packard crimpers. if anyone is interested send me a PM
