Electrical upgrade

Ok guys, based on the advice of some of you helpful folk, I've gone and purchased an EZ 21 circuit harness. I also decided that it's time to upgrade the gauges as well. I'll be using some Ultra-Lite II's. I've got everything together that I think I'll need, but since others have already upgraded using this harness, I'm asking for any documentation or advice that you guys have to make this go as smoothly as possible. Pictures, notes, anything would be much appreciated.

My car is a 73 Duster with 4 speed transmission. Alternator is 60 Amp (I think).
