Here is the wiring diagram for each, should be able to just plug it in and go.

View attachment 4.3 Merc wiring 1.pdf View attachment OMC Wiring Diag.pdf 10.pdf

Not sure why, but just click the blank space to the left of the thumbnail for the Merc diagram, it just doesn't show a preview, but it's there.
