any advice would be greatly appreciated
The harness will definitely need to be replaced and the ECM will need to be reprogrammed, at best. If the MPI engine was from a marine application, you may be able to use the ECM but it won't be a match to the boat, like the MC programming. If you know someone who can do data acquisition and programming, that may work but to do a custom program right, you would need to know exhaust temperatures, emissions and load.
