This red one is a VERY old edition (#880), perfect for '80-86 trucks. It includes many older diagrams not found in later editions. For '87-96 trucks, a
red cover that goes to '96 (also
here), or an EARLY blue cover (as shown #36058 ) would be much better because they contain much more info about EFIs, including superior wiring diagrams.
Unfortunately, the LATEST blue-cover edition has deleted much of this info, and its wiring diagrams aren't worth having, except as a crutch until you can find one of the older editions. Even worse: there's NO difference on the cover, so the only way to tell which version a blue cover is would be to OPEN the book & look at the wiring diagrams. If you're communicating with an eBay (or other online) seller, ask him what's on page 12-63. If he says it's '92-later F/Bronco diagram 13 of 13, that's the version you want. If he says it doesn't HAVE a page with that number...

The later version (with crappy wiring diagrams) ends at p.12-54, which is followed by a glossary of engine rebuilding terms.
These manuals are often available on eBay for less than $10 shipped, but make sure you're bidding on (or buying) the edition you really want. All the blue covers are 80-96 so they're very hard to distinguish, but there are MANY red covers. To see what's available right now,

I have never used or visited
https://charm.li/ , but it purports to be a totally-free library of service manuals for all years, makes, & models. Use your own judgment & caution before clicking that link.
MotorCraft Service also has some free resources, but not many apply to pre-'02 vehicles.
If you don't have an owner guide, download the
'96 or '97 PDF free from Ford or through
the MotorCraft Service site, also free. For ~$30, Ford will give you
access to all service manuals, TSBs, FSAs (recalls), EVTMs (wiring), & PCEDs (engine & emission management) for 3 days, but I haven't checked what's actually available for these trucks.

Ford disk images can be mounted to a virtual drive, and installed to a HDD partition with its own drive letter for use without burning an actual disk, but having the disk is a worthwhile safety net, in case of HDD failure or infection. For instructions on installation & use:
