OBD 1 port on 1989 f250 ?

I can't find the connector to plug my scan tool in. That F250 1989 4x4 has a check engine light on.
Didn't see anything under the dash.. should have a odbc 1 connector somewhere. I did find what looks to be like the computer.
Any one how where the OBD1 port is on 1989 F250 4X4.?

TIA, Ted O.

This is a '95, but yours should be similar...

Getting trouble codes

you can get codes with just a jumper wire see www.fordfuelinjection.com under getting codes. You count the engine light blinks and look up the codes at the above web site. Just because you gat a code doesn't mean its that part but its a start. First test wires and the parts. Start with the lower codes first and reset the computer each time. Unhook the ground on battery for ten minutes. Will take a liitl while before it runs ok, EEC needs to re learn your driving habits.
