It's also really nice to not have to re-use any of the original connectors, saves time not having to strip them off the old harness and you get brand new terminals. In my AA kit the only connector I had to re-use was for the wiper motor. I kept my old connectors just in case, I just clipped them off. I've been taking the wire ends out of them as I have free time, but it takes longer than you'd expect!
The quality of the AA kit is better than what I've seen with the other more generic kits. Obviously it's not OE, so the AA kit isn't right for everybody, but especially if you're modernizing and upgrading your electronics it's a really great kit. I plan to add EFI at some point so I wanted to have a quality harness that took that into account, rather than trying to add it into a more original style harness.
