Be very careful with that statement above. Lead Head is correct, the California emission trucks with 7.5L engines (<15,000 lb. GVW) were OBD-II starting in 1996. I know Massachusetts is pretty stringent on their emission requirements as well, but I have no documentation they were OBD-II as well.
I guess I was getting ahead of myself, since he said he didn't find an OBDII connector then there WAS a very good chance it was OBDI....
I'll just shut the hell up and leave it to the pros!!!!
I know what would make you feel better: go to Conanski and ask him to hit you on the head with the hammer he uses on me. My head, by this time, has made a nice, flat spot in that hammer so you shouldn't feel much pain but, for some reason, when he does this the world is right again, everything is puppies, unicorns, and rainbows.
I'd rather have these lumps than be wrong the rest of my life

Massachusetts adopted California emissions in around '94 I believe.
There are also some other exceptions/oddities. For example, the 1994.5-1995 7.3 PSD trucks have both the EEC-IV test port under the hood, and an OBD-II port inside - but it doesn't work from the factory. You need to have it flashed to enable OBD-II functionality.
