The F250's (over ~8500 GVWR) didn't have to go OBD-II at the same time as the F150's, so your truck is probably still OBD-I and has the diagnostic port under the hood.
Old thread, but seeing as how Im now dealing with this exact issue, I must say that this is the dumbest thing I have ever seen....even for Ford. Just got the truck and Im already sick of the Ford B.S.....OBDI on a 97.....gotta be fkn kiddin me.....

OBD I beats the heck out of OBD II. I would not have a truck with OBD II.
And why exactly would that be? OBDII systems allow much more specific failure information, including specific cylinder. It has better memory, and uses a much easier to read system then a series of flashes on the guage cluster.
Dont even get me STARTED on trying to custom TUNE an ECM after any serious modifications!
OBDI is just too limited. There is a reason it had such a short run before II came out.

Blame it on the feds, not Ford. Anything under 8500 GVW had to go OBD-II while anything over 8500 GVW didn't, so ford had to go OBD-II on F150s.
Easier to work on.
OBD II systems are too complicated.

So does the OBD I system tell you a specific cylinder that is bad and what is wrong with it.

Not true, the flashes can be read if you are out without your scanner as emergency back up. There can not be any easier system to read than the OBD I system.

The OBD I system is very good the way it is and you can write your own program to run it. Try that with an OBD II system.

I see you have no idea why they went to OBD II and it was not because it was too limited. You can make all kinds of changes to the OBD I computer program to run any modifications!
OK, I see a simple solution here...... Just sell, or give away all the Fords you have that are OBD I, then spend the bucks to get LATER models that have your precious OBD II systems..
