Question about 1990 Ford F250
Where is the engine code test plug located on a 1990 Ford F-250?
1990 was NOT OBDII, but it WAS an OBD or OBDI.
OBDII (2), was not in use until 1996, actually late 1995 they started to appear, since mandate was for all North American vehicles to have them in place by 1996!
Anyway, Communication port for OBD is under the hood for all pre 1996 Fords.
