OBDII on Ford Pickups

OBD2 PCMs were mandated by the federal government in the US for all 1996 light duty vehicles. There are some vehicles that had partial OBD2 capabilities in 94-95, especially for the California market but they were still technically OBD1 as they did not have full OBD2 functionality. An example would be the 95 Corvette and F-body cars. They had OBD2 ports, PCMs with FLASH memory and the capability to be reprogrammed from the port, and most of the emission standards for OBD2 programmed into them, but still used all the OBD1 protocols for GM otherwise.
I couldn't tell you if any Ford vehicles had something similar as I'm not that familiar with their OBD1 systems as I've never owned any of their 95 and earlier vehicles. Maybe there are some Ford guys on here with some computer tuning experience that might have more info.

And the 1964.5 Mustang had a generator not alternator. Something about Mustangs.
My 1994 Bronco had OBD1, a friends F150 had OBD2 in 1995. I would imagine at least the F150/Bronco for the 1995 Model Year was OBD2.
1996 F250 good old OBD1, and no airbags.

We had a 95 Camaro about 8 years ago. Thing was a pain. Couldn't read it via either OBD protocol. Thankfully the only code it ever threw was...idk, but at emissions time we just reset the comp via battery disconnect and went straight to the emissions place. They couldn't scan it, either. No light, no problem, and it passed the sniff test. Lol. Keep that in mind, guys. 94, buy. 96, buy. 95, stay away if emissions is an issue for you.
Never had any issues with my 95 K1500 I sold to my ex and a 95 Suburban I owned for a while. Both worked fine via OBD1 and even have a good amount of live data if you have the right scanner. So not all 95s are bad.
Same on my 97 and 98 F350 and F-Super Duty

My bad, I was specifically referring to the F-body cars. They were OBD1.5, and from what I've read, even dealers just threw parts at them because they were difficult to talk to if not impossible.
But yes, the 95 trucks were still pure OBD1.
GM Tech 2 & most Snap-on scan tools have no issue communicating with GM 8192 baud protocol.
The only thing you need to read a 95 Corvette or Fbody PCM is a OBD2 style connector and an OBD1 compatible reader. Or just use a jumper connector and directly connect to the pins on the OBD2 port. I've scanned and data logged many 95 Y and F bodies over the years and never had any issues.
The problem is when you take it to a auto store and they look at the connector and say "Well, its obviously OBD2, let me get my OBD2 reader" which almost 100% of the time will not work. I could see the same problem taking it to some emissions testing thing in states that have that nonsense. Fortunately we don't have that where I am from but I would make sure that whoever was running the test that they need to use OBD1 protocols for their testing, not OBD2.
And aside from the Y and F bodies, no other vehicles from GM have this setup. All other GM vehicles in 94-95 still had the OBD1 connector and the older style PCMs with the MEMCAL and the EPROM chips.
I had heard some 94 Corvettes had the OBD2 port but I've never personally seen one. My 94 Camaro still has the OBD1 port but the PCM is the FLASH memory one that can be programmed from the port, it was used in all the 94-95 LT1 engines. 94-97 turned out some weird stuff in the transition from OBD1 to OBD2, you really have to pay attention to what you have in these years, there are so many special exceptions.
