The availability of diagrams will depend on a few variables including the year of your vehicle and how much of the vehicle is factory original. For original equipment diagrams, check your local auto parts stores for repair books for your specific vehicle published by companies such as Chilton's or Haynes. You may also order or download many repair manuals and individual diagrams online.

You can get an adapter plug for most Ford and GM trucks that just plugs in to the tail light wiring.
The best source for a wiring diagram is a good repair manual. There are repair manuals for your vehicle sold at most auto parts stores.

the Hanes manual sold at oreilly auto parts also chiltons manuals have it. Just check with part stores and ask for them. I prefer the hanes best.
In general the diagrams (and complete ones, at that) can be found in the owner's manual for the vehicle.
The vacuum line diagram is not available for free. It will have to come from the Ford service book, or from a Ford dealer.
