Mechanical to electronic engine conversion

It seems that the people at Mawk make the conversion pretty simple as well with their wiring harness...all these resources you men have given me, gives me and my old truck new found piece of mind. I really appreciate the input!!!! This isnt something that I plan on doing tomorrow(knock on wood). As long as the old 3406 keeps chugging away, Im gonna run her. With the close near future holding an inframe though, I really think the conversion would be the way to go, in order to get ahead of the game and save money in the long run. Another question: The EOBRs..... are there particulars when it comes to the ECMs, that they will adapt to? Say 70 pin vs 40. I know that the 3406E is a tried tested and true engine over the C15. Im wondering though if the E Model CATs electronic characteristics would support an EOBR?

 

Contacted qualcomm and they no longer make a GPS type EOBR....I know there are other manufacturers but no one I've found makes a GPS version
