Which diagnostic interface di I have?
Evening all. New poster, long-time lurker.
I've got a decent car-pc built as far as entertainment and basic travel utilities go, but I'm looking to expand into on-board diagnostics.
The trouble is, my vehicle is a custom built 1994 Ford E-250 (former ambulance). And I can't find out what interface it uses for diagnostics!
From poking around, I've found BOTH an OBD (hopefully OBD=II?) port, and an EEC-IV port. But as of yet I don't know which one works. Is there a guaranteed (but cheap) way to find out which one I should be using?
And if it's the EEC-IV port, is there a cable to connect it to my car-pc, and software to utilize it?
Thanks in advance!
