my nephew is trying to get a field truck for the farm up and running. Apparently an engine swap was done, removing the original 1993 E7 350 with a 1997 E7 350. Whoever did it just cut the harness to the fuel pump. The wires on the new engine pump don't jive with the cab wires, colors & wire numbers don't match. I know this is kind of vague but if anyone can chime in I would be most grateful.
