I finally found out why the data link isn't responding. After checking the entire electrical system including load testing I was running out of options and it was down to the eprom so I phoned the dealer and found out that the epron was out of a 1995 not 1992.
The dealer informed me that the part is obsolete and that the replacement part requires the original part # for comparison. Of course I don't have the original part # and am again at a loss of what to do. I am going to try and retrieve the original info. From the dealer. I have a 1992 F3500 454 4x4 dually with a 4 speed automatic tranny.
