If you plan to keep the truck and work on it yourself, buy an Electrical and Vacuum Troubleshooting Manual (EVTM). It will have all the electrical diagrams, connector and component locations, connector pinouts, etc. It will be the best money you'll spend on the truck (trust me).

"1994 Bronco/Light Truck/Super Electrical & Vacuum Troubleshooting Manual"
"1995 F-Series Electrical & Vacuum Troubleshooting Manual"
"1996 F-Series/Super Duty Electrical & Vacuum Troubleshooting Manual"
"1997 F-Ser/Super Duty Electrical & Vacuum Troubleshooting Manual"

Cheers!

Used to be able to find them all on a CD on ebay cheap. Ford service manual, EVTM and the smog manual for a single year for less than $10.

It does help to have all the manuals.

I think I have all of them and each and every one has come in handy...

You should still be able to find them on ebay (CD versions), but there's nothing like having a paper one to flip through especially when having to look at multiple sections. I have 95 and 96 factory manuals on CDs and the 94 and 97 in paper. Cheers!

Mind if I ask what all of the manuals are?
I think I have them all.

Powertrain & Drivetrain
Body, Chasis
Preliminary Specification Book
Specidication Book
Electrical & Vacuum Troubleshooting Manual
Technical Service Bulliten Index

The rest of the books are the owner's manual and AIC manuals.

To be complete it looks like you also need the Powertrain Control and Emissions Diagnosis (PCED) manual set (Multiple volumes). It also is on the CD with the others too (I only have 95 and 96 versions of these and they're on CD). :D
Cheers!

Oh yeah, I forgot about that one, I have never had a need for it.

The best wiring diagram I've come across (for my '96, at least) is FCS-12135-96 published by Ford Technical Publications Department, Ford Customer Service Division. It's printed on 17 x 24 paper so it's easy to read. :cool:
