you use an obd1 scanner or a paperclip and count flashes.

i recommend the scanner method.

The over 8500 GVWR trucks did not have to comply with OBD-II at the same time as the light duty vehicles, so the 97 F250 HD and heavier trucks have carryover OBD-I systems.

It could be a really early one, like a 96.5.

Hey mang, this is an OBD1 port, is that what you see?

Yep, you have to connect both plugs. Or else just use a wire to ground the little grey plug, get inside, turn your key to the on position, and count the light flashes.

I can offer extensive advice on any codes it throws.

He pulled code 72 and 33. of 'em!
Told him to replace his vacuum line to the MAP and clean his EGR, hopefully that cures both of 'em!
