A full set of Ford factory shop manuals for year 2000 Econoline. Includes wiring diagrams manual (worth it just for that book’s usefulness). I imagine they’d be basically the same for other similar vintage years (I got them for my 1998). $35 + shipping from Philadelphia area.
I agree with JWA. I still have the 3 out of 4 manuals I bought for my old 1990 E series van (sold in early 2007). They are so good - and were so hard to find. I'm hesitant to let them go. I have a couple of 2009 manuals bought mainly because I found them cheap. I'd love to find a set for my 1992. Especially the vacuum manual since the cruise control in my van is non-op and my WAG is it's vacuum related. And looking under the hood/doghouse of a 7.3 IDI van is daunting. No room and wires and hoses running everywhere.
A little off topic, but I just purchased a 2019 Ford Transit shop manual on eBay for $35. It came as a DVD. Looking it over, it is 8,496 pages! I haven’t been brave enough to look at the wiring diagram yet. That’s a lot of paper in a bound manual.
