Hi, I'm an old guy with a 1999 very stock 2.5, auto, ranger. Like many here I am looking for help with shooting an electrical problem. My problem is lack of information, OTC 'repair" manuals are quite lacking for electrical issues.
Welcome to R-F! Try a quick search on ebay for a wiring diagram for your truck. Sometimes you can find a pretty good deal. I purchased mine from a fellow member who bought one for both of our years in a set and I bought the other one.
I did give E-Bay a look and only a two volume shop manual for my 1999 year. Pretty pricey at that. I also have a more detail post in the technical section. Not sure what years are identical to the 1999.
