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.

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.

my '86 DLC was on the passenger side of the engine compartment... the odd shaped connector was red...
