Diagnostic port?
Hey all, I posted this in another section also but figured maybe I could get some help in here too. I've got a 97 F-350 with the 460. I bought a Superchips tuner for it but cant find the diagnostic connector. Where is this thing?? All I can find under the hood is the eec test plug? Under the dash, nothing. What gives?

It will be to the right or left of the steering colume at knee level.

I appreciate the responses guys but unfortunatly there's no plug under the dash. I've worked with the tuners on diesels and on my Lightning and they've always been exactly where you're describing. The only thing I can find that remotely resembles an OBD2 port is on the driver side inner fender and is labeled EEC test, and the plugs dont come close to fitting together. Maybe the tuner that is supposed to work for my truck was mis-labeled.

The F350 with a 460 is not OBD2 (its a heavy duty application that didn't fall under the Fed requirement for passenger vehicles to be OBD2 by 1996). It's going to require a chip, not a tuner. There are some of them that had it, and oddly enough it was on the passenger side.

I was just thinking that, the 3/4 and 1 tons fall out side of the emissions requirements. I guess it would depend on the EEC type if it is easily flashable. The older EEC-IV I believe needed to be re-prommed to flash, while all of the EEC-Vs were EEPROM.

Called Superchips tech guys. They said most of the later 97's were OBD2 while the early ones were not. Mine is a May truck, go figure! lol O'well, I'll just bump my timing and try to figure out a way to up the line pressure for the trans a bit. Thanks guys.
