I need to source a wiring diagram for '97 Expedition. I've gotta reinstall an aftermarket h/u. Looks like previous "professional" hacked off the wiring plug. I am certain one once lived there. So what I need is schematic or writeup of what goes where. Help!

 

you might try autozone.com in the DIY part repair manuals. there may not be what you need now but there is some good stuff in there .

hope this helps you out. This is for a 98 expedition.
