MEFI 3 plug pin map

Anyone have the pin configuration for the ECU plugs for a 575sci wiring harness. I am trying to rework a wiring harness to the 575sci configuration. I have the harness schematic but not the location of the wires in the connector plug. I can't sem to find it through mercruiser or anyone else.

Are you going from MEFI3 to PCM555 ecu?

Actually I'm installing a 575 sci system on my old 502mpi block after a complete rebuild so I am going from a MEFI1 to a MEFI3.

I have a 575sci if there is anything in particular I can look at for ya or possibly take a picture of.

I appreciate the offer but you would have to have a lot of time on your hands. If I can't find a pin map then I'll have to find one locally and open the back of the J1 & J2 plugs and correspond the wire colors to the number next to each pinhole.
