Krusty thanks. I'm gonna go look under the front hood and then pull the engine hatch
if I have to. First I'll go look for images of EECIV
Get off the phone and drive!

It is made up of two connectors. The main one is about 2" x 1"
and kind of shaped like a trapezoid. It will probably only have 3 of the connector pins used. The second connector is a one wire connector only. They are usually plugged into a black plastic holder that says EEC-IV on it.

thanks to everyone here, I found it! Very hidden, in a black plastic cap covered in dirt inside the engine bay clipped to the wall on the left side.
big sigh of relieve. old OBD-i. I ordered an OBD-i to -ii connector which has maybe 10 inches of cable, so that I can plug in and close the hatch and still have access to the EEC-IV

I went through both of the Ford manuals on the chassis and there is no mention
of an OBD plug or diagnostics plug anywhere.
OBD-1 where your right knee would be, then forward.

Though OBD-II is much more.... capable
ON my old obd-1 GM I could read error codes with a paper clip..
Home is where I park it.

The location of OBD plugs (within 2' of the steering wheel) wasn't standardized till 1996, and even then only for passenger cars. Earlier cars, and RV's up through about '99...crapshoot for location and type of connector. And then of course the "split-year" situation with RVs adds another layer of ??? to the whole thing. My last RV (Class C) was an '88 model RV on an '87 model chassis that was built in '86! Glad the OP was able to find it with help from the forum.

ya, it is extremely helpful to be able to lean on others here who have answers. Good luck asking a dealer or service place, they seem to understand basic questions only.

On a Ford, you needed the paper clip and a test light.

the F53 chassis in 1997 was still running EEC IV engine control system due to the GVW of the vehicle exempting it from OBDII requirements. You'll find the EEC IV (DLC) connector on the passenger side near the starter relay. Location varies since coach builder may move it, but should be in that area.
OBD-II became mandatory on a "light duty" vehicles in 1996MY. EEC-V came out about that time. It was necessary to contain all of the extra code mandated by the government.
EEC-IV was carried forward on vehicles that did not require OBD-II for a few years (Lower cost.)
Today, more than 50% of the software in a typical PCM is for diagnostics and monitoring.
