OBD-i and OBD-ii did a '96-'97 F53 ever have diagnostic plug

It's probably to late but I bought a OBD 1015 reader that plugs into the wires of the EEC. There are two ways to read it. One is by beep counting or the other is by light blinking. It worked great for me. My biggest problem was I was to tight to buy the extention cable that would have made my life so much better.

But what I ended up doing was hooking the scanner up under the doghouse to where I could see the light blinking. Then I took my Ipad and took a movie of the blinks. I then cqme into the house and replayed the video until I had the code. once I got the code I knew exactly what to do to repair my Motorhome.

Mine also was a 1996 Damon that didn't get the OBD upgrade so I have to live with the EEC. I highly recomend the OBD 1015 reader if you can find one. Life saver for the DIY'ers.

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.

ON my old obd-1 GM I could read error codes with a paper clip..

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

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.

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.

high on the steering column and under the dash sounds impossible to get access.

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.

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

Krusty has is absolutely correct.

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.
