My "new" '74 Duster- or why I need a project like a hole in the head

That's great to hear. I've been considering one of their universal harnesses for my 66 but wanted to hear from someone who's actually used one. I figured if nothing else, it'll be a good starting point for what I'm doing with the car.

Hell, finding quality butt splice connectors even seems difficult these days. I picked up some un-insulated ones yesterday from Napa and the one I used almost broke in half when I crimped it. I'm assuming the terminals/connectors in the AA kit were good quality?

I don't use butt splices any more if at all possible. I have switched over to solder splices. You just use a heat gun to shrink the sleeves which have sealant at either end to keep the elements out and the solder melts and wicks up the wires. Fist saw them when I worked in an airplane manufacturer and started using them. Never looked back. Stronger connection that wont corrode and go green in a few years from moisture
