looking for literature on fixing electric door parts

I have a 92' Ford Ranger with 2.9 V6 and 4WD. I need to do some work on the interior of both doors: electric door locks, lock cylinder, linkage,door knobs, etc. My Chilton's manual does not have enough information on this. Are there any other books, websites, manuals that explain this in greater detail?

you can search after you register...it's free. I think the Explorer forum had more stuff, but the Ranger forum might have something too...
