587 657 engine swap question.

Hey everyone first post here. I've been working on seadoos for a while but encountered this today. Customer brought in a 1993 seadoo xp with a blown 657 (non-x) engine. I had a perfect 587 from a 1996 spi that I swapped in. I did ll the normal stuff, jet pump service and engine alignment, new fuel and oil lines, carb rebuild, but when I went to swap electronics the 96 spi has the newer 4 wire stator setup with the plug, whereas the 93 650 has the old 4 wire that has to be removed from the ebox. The wires don't all match up and I'm wondering where I connect the new wires?

Can someone at least tell me if it is a clean swap if I swap stator from the 657 to the 587? I'd rather not do this if there's an easier way in the box but just need to know.
