On the starboard rear of the boat, under the edge of the swim platform is a series of thru-hull fittings, can someone direct me which one is which, all of mine are disconnected. Should be 4 total

Scupper hose and fitting should be larger. If all the other hoses are sitting there disconnected from the thru hull fittings and are the same size it shouldn't really matter which hose connects to which thru hull fitting.

our 2005 has 4 and I cant remember what each is, but they will match up with the hose size. If you have 4, it should be A/C discharge, starboard bilge pump, cabin bilge pump, and shower sump.
