Wiring diagram for electric locks & windows

Just bought a couple of used doors off a 91 Ford Econoline conversion van for my 89 U-Haul Econoline and they have electric windows and door locks, after I have them painted I would like to wire them up. Does anyone have a diagram for this? I was told the conection might be already in the wiring harness for these hook-ups. Is this true?
Thanks, Gary

If the wrecking yard left all the pigtails intact, you will find their matching counterparts under the dash or behind the kickpanels. No real diagram for THIS, unless youre looking to wire up solid...

Great advice...was a piece of cake...works GREAT! Thank You
