The salvage yards will have that information. In particular, there were four different factory mounting styles. The most common one on trucks used four tiny holes in the faceplate, two on each side, about an inch apart. You need special tools to remove those radios. Auto parts stores sell them for about 8 bucks a pair.
You should see a black plug in the dash, with a red insert. It's about an inch long by 3/4" wide, and has two rows of pins. That is the only plug you need to run the radio. It has speaker, power, and lighting wires in it. That plug goes in the lower corner of the radio. One of the other sockets is for the factory CD changer. If your changer is an aftermarket unit, it may have its own separate wiring, and it just plugs into the radio antenna cable.
I've repaired a lot of the Ford cd / cassette combo radios. They are not a bad radio, but there's two versions of them. The one I always run into develops intermittent display, and they can be real frustrating to repair. I have the replacement boards that the authorized repair centers install, but those are built the same way as the originals and will develop the same problem in a few years. The permanent way to fix them is to find the bad connections and resolder them. There's a few Chrysler radios that do this too, and there's either one or three places to look. On the Fords, there's at least 80 places that can cause the problem. When dealers send me a radio for this problem, I tell them I'm keeping it for two weeks. Very often after test-running them, the problem reappears more than a week later, and I have to start all over. THAT'S why they're so frustrating.
You definitely do not want the in-dash 6-disc CD changer. That was a major disaster. All of Chrysler's 6-disc in-dash and add-on changers go to a lock mode automatically when power is removed to keep everything in time. The Chrysler four-disc, and the Ford 6-disc do not. The Ford unit will not survive shipping without a special, very complicated bracket installed to hold everything in position. It is probably the number one item on eBay that the seller is convinced he sold a properly-working radio and the buy got a non-working one. Even the replacement changer mechanisms have a large sticker on them that says "scrap if dropped". There's quality for you! I would guess the Chrysler 4-disc units only survive shipping about half of the time. There's a second version of the Ford cd / cassette combo that doesn't have the intermittent display problem, but they do have volume problems. The first version has a serial number that looks like it was put on the sticker with a typewriter. The letters are about 1/8" high and the sticker feels like regular paper. On the second version, the serial number is much longer, the letters are about 1/16" high, and they're printed on the bottom of a long shiny label.
I've only worked on a couple of Ford cassette radios, again for intermittent display, but those were not real frustrating. Haven't worked on any cd-only radios. Either they weren't real popular or they don't break down. Knowing how they're designed and built, I suspect they weren't real popular.
Be aware too, that to keep all the lucrative repair business for themselves, GM stopped allowing us to buy radio service manuals after the '94 model year, and Ford did that after the '97 models. You'll be tied to the dealer and the two grossly-over-priced repair centers. There are other repair shops now but, like me, they have to figure out the problems without having a service manual to look at.
