Flashing od off light

Hi, new to fte, I have a 1990 f250 7.3 diesel with e4od. My od off light started flashing Saturday morning when I started it up, it doesn't go off at all. I drove it about 15 miles to my farm and parked it. I know I need to read code but cant find access port. I tried disconnecting battery cables, checked for loose wires, tach and speedometer seem to be ok. I could use some suggestions. By the way it was my only transportion, I bought a 08 Ford Focus Saturday, needed something to drive.

MY 93 F350 DIESEL DID THAT A FEW YRS AGO AND IT TURNED OUT TO BE JUST A BAD SWITCH. JUST A THOUGHT.
