for the most part,it's pretty self explanatory....between the number of bolts for each part-to-frame...slack in the wiring/routing,and the plugs should be self explanatory as well...meaning they will all only plug into one place....fail-safe.
I had an 04 a few years ago,and went through a similar dilema...I have a 2000 now,and the wiring is very easy to figure out.
You can figure this out....if I can,you can.
