The step by step installation instructions and schematic diagrams should have been included with the upgrade kit...just keep all the small parts organized and in the plastic bags until the are needed...the 200 amp alternator is very heavy and it is recommend to use a hoist to lower it in place (I also recommend having a friend operate the hoist and lower it into place while you try to get that 10 inch bolt through (very tight tolerances...).
I literally just did this today, but without a hoist...but the entire time, I was thinking "Where's my *** ***** ********** piece of **** hoist when you need one!?" So, let me serve as proof that you can do it all without, but it wasn't fun. Not even a little. Now as for those instructions, they're pretty clear as you get going through it. I like to keep the parts packing list right by the spread of all the parts that came with the kit so I can go reference it to which part bag I need, then I keep the instructions and fold-out drawing near where I'm working. Pretty much read a paragraph section, observe the figure it references, and then put that together in reality. Pay attention to items marked as "Reuse," "discard," or "included" as that will help you know what parts you're needing to grab. As well, heed their "DO NOT TIGHTEN" warnings, as you'll want those parts to fit loosely until everything's together and you're then tensioning the belts near the end (just don't forget to go back and tighten them...it may help to read through the instructions again at the end and physically touch every nut/bolt it told you to not tighten earlier, in order to make sure you got them all.)
