how can i tell if my 1995 2.3l is obd1 or obd2?

Hey guys I have a 1997 ranger 2.3l and I recently bought and rebuilt a 1995 2.3l which came from a ranger. I'm getting ready to drop in the 95' but I'm worried that its an obd1 and won't work in my truck. I don't have any info about the production date of the original truck that the 1995 2.3 came from. So is there anyway I can identify if my 1995 2.3 is obd1 or obd2? Thanks for the help.

If it did indeed come out of a 95' Model, it IS OBD-II for sure, no doubt.

I know for a fact its a 95' I looked up the head casting number to verify it.
