OBD-I or OBD-II on 1997 F350 SD
I just joined your group today, so I hope I am in the right slot.
I have a 1998 Fleetwood Motorhome on a 1997 Ford chasis 460 cu in.
I have wanted to analyze a problem, but have unable to find the OBDII plug for test. Have spent 2 or 3 hours looking everywhere around str. clm. under dash, etc.
Just today reading your forum there seems to be a dispute if this even has the OBDII and EECIV system.
Some tect data: Vin# 3FCMF53G9VJA28746
Thanks for any help. v

Thanks Pony Driver, I will coninue to look for the OBDII test plug. I am probably in the wrong group of threads for my problem, but maybe able to steer me to the right place.
As I mention 1998 MH on 97 350ESuper Duty chasis, any member had the experience to locate the PCM, they may hide them in different places, but thought I would ask to save time, I don't get around very well, so the less bending the better.

VDW- I wish I could remember where it was that I had read it, but I think this has been asked before on a Ford truck forum and though '96-up should be OBDII it seemed that the vehicle they were dealing with was a '97 F-250 or F-350 Super Duty W/460. It seemed that it didn't have the OBDII because it was still the old body. I could be all wet, but at least that was the truck they were talking about. It has been at least 2 years ago. Whether E or F, they both may well be the same. Since it's an E, the port should be in that area, not hidden away because I think that was one of the standardization dictates when OBDII came out.
Just went back and re-read your original post and see that one place you list it as "F" and another place as "E". Is it a class A or class C?

Well, found plexi-glass plate with info stickers that had been covered with some kind of tape, scrapped and found on emmissions sticker that this is a OBD-I and it is a mfg. date of 12-1997, and made in Mexico.
Now to find the EEC-IV and the test plug (not sure what the plug looks like) there is a small plug, maybe an inch x 1/2, with only two wires to it.
ProjectSHO89, right on the money, and thanks to the other contributors also.
Note: I previously called two Ford Truck Dealers SD, and they insisted that it was a OBDII. and by law.

Quick google for OBD-I test connector

Why did you need to find the PCM ?
If memory serves me correctly, the 1996 mandate for OBD-II standard was for cars. This would mean trucks ( greater than 8K plates ) would have been exempt at the time. Thought it was due to EPA testing standardization.

Now I know what to look for on that test lead, thanks for that effort. The reason for looking for the PCM, as I have considered a performance chip and I think thats where they plug to. The MH is a 34' w/slide, I installed the Banks when it was new and that did help, but could used just a touch more HP so as not to shift down out of OD on slight dips. If any increase in milage would be an welcome extra, I get between 6 and 7 1/2, but in wind ruff condition could be down to 5 mpg.
This is a great forum, I wish I would have found it long ago, you tech. guys are are something else.

Don't know if Banks has the shift commander for your configuration, if Trans shift duration is the target.
This might be easier than a SuperChip with a program for your MY / Config. You can Try Mike Troyer at Troyer Performance to see if he still has the plug in SuperChips, this would require the conformal coating to be removed on the PCM. The PCM should be on the firewall, if it is like the F-150 line, it would be mounted so wires can be accessed from both sides ( as if mounted in a mounting hole in the firewall ).
Don't know where for sure on that old of a chassis. Dad's is a 2001 Itasca 38'.

Thanks SSCULLY, had to take a day off, bad back. Looked again today and found a large wire loom going into a cover in front of the steer column on the interior floor against the fire wall, about 3"x5"x1 1/2" high or so, tried to get the cover off, but the snaps are perty secure. Makeing a tool tonight that might help. "that might be the connection".
I did have the Banks Trans-Command installed with the Headers etc. I see Performance Chip advertisers on this forum. I have not run down Mike Troyer yet, I think the cost of that one would put me out of the market. Some of the advertizers are showing a $69.00 one, that I could handle, but have any of our members commented on these? I still assume that they plug directly into the PCM, which I still have to find.

If a "chip" only costs 70.00, pass on it. It is most likely junk.
A good tune made for your PCM version is going to run a few hundred dollars, to actually get something out of it.
The other thing to keep in mind, is to get any real HP out of a tune, you are going to be running mid grade or premium. Not that great of an idea on a RV.
Not much timing advance to be had on 87 octane.
