I have 5.9 Cummins that I pulled from a 1999 F650 now installed in my 08 SDF250. The problem I have is identifying the ECM wires out of the 99 to convert to the 08. I have called Our local Ford Commercial Truck Center for a wire diagram....but they have none on there computer...It's to old. There are shop service manuals out there....just have to find one.
ANY IDEAS???????????????

 

Why not use a Dodge application ecm? The dodge one is better suited for a pickup than the f650 ecm and you can use programmers and such on a dodge ecm where the ford one you cant.
