Thanks for the note Jim. As we've discussed, I believe that this should work fine with the 8V's. I've looked at the Prevost wiring diagrams, and it indicates the 8V ddec has the J1708/J1587 data, but on a different connector. I'd like to get ahold of a cable or adapter first, and then try to run on an 8V to see if it's going to work for you first.

I would guess the major difference would be that the earlier DDEC's will send a smaller subset of the messages, but until I capture and analyze some 8V data, I won't know for sure.
