Wiring for 1999 Dodge Dakota

I used the wiring Diagram to install an aftermarket Alpine Deck from this site for my Dakota Club Cab and it was not the same inside the dash as the diagram was showing.  Most of the are off or do not exist.

I cut the orginal harnsesss of inside the truck rather than buying the adapters (just being cheap), i did save them though and could throw them back on.  Anyway any suggestions as to trying to figure out this wiring, as of now my dash is in pieces an I would like to get it back together.  Basically if any one could provide me with the correct wiring color codes, or a way to figure them out I would be thankful.

Thanks
