I've rewired two cars with AAW kits, one A and one B body. The wire they use is nice quality (TXL) but the rest of it kinda sucks. All their kits are based off GM wiring components and 'made to work' in other makes. To be honest, the '68-'70 B body one was way better than the A body one. I had done the B first so I figured the A would be the same but it was totally different and not for the better.
First, I trashed their fuse box which if I had to guess was sourced from an '80s GM product. It's this unwieldy two-piece thing that takes up way more room than it should. Everything in it is permanently bussed together which I can't stand. It also hangs off the back of the bulkhead right next to the heater box so forget about ever trying to get at anything in there. I don't know how anyone in their 'engineering' dept. would think that design was OK for an A body Chrysler product because it wasn't.
The main issue with the AAW A harness is that it covers everything from '67-up so you end up with a bunch of extra wire. The ignition key position changed in 1970 to the column rather than the dash but no matter, they stuck both styles in there. Unless you're willing to unpin/cut/splice the extra ignition harness you'll have a bunch of wire just sitting there taking up space. Same with the backup lamps/NSS wiring and whatever else changed between those years. Every circuit variation for all years is there whether you want it or not.
Some people might like the fact that they give you harnesses for accesory stuff like power windows and seats but again, most of the time it's just extra wire creating clutter. I don't know of any A bodies that normally had those options anyway so in my estimation they should offer it as an add on rather than a standard item. Leave those gee gaws for the street rod crowd.
If I had to make the choice again I would not buy the same kit. I'd probably just make a new one myself since that's essentially what I ended up doing after taking theirs apart to make it work the way I wanted. I think I ended up using about a third of what was provided and most of it was just the wire.
Live and learn.
