Update:
Ok, so here is where I stand: I got everything hooked up, went to start it and all I got was an ABS light and no fuel pump cycling. I printed up some Alldata wiring diagrams and saw that I was missing a wire on the battery junction box. Hooked that up, blam, normal key-on functions (all idiot lights, fuel pump cycling, etc). I went to crank it over and the starter sounds slow and wouldn't start. Bummer. Pulled the starter, had a local parts house test it, passed with flying colors. I posted this video of the problem on a few other forums:
YouTube - 2000 Mustang GT starting problem
and I was told to look into battery. WHile the battery has a decent charge (12.59v on my voltmeter), it may not be providing enough amps to get the starter going. Now I have an excuse to get an Optima battery, so once I get off of work at 8am, I'm headed to Autozone to pick one up.
Power Steering issue: I picked up a new pump yesterday at Kragen's, however I need to find some way of pressing on my pulley without screwing up the pump like on the stock one. My buddy was pressing on the pulley on the stock pulley when the shaft decided to exit the back of the pump instead of letting the pulley be pressed on.
Once I have these issues solved, she'll be back on the road.
