Ben - From what I hear the Johnson 4 strokes require OMC/BOMB rigging (wiring harness, System check tach, gauges, prop) - not suzuki. I have heard Ficht rigging after 99 mates up, but you should be asking this question to the dealer. What I have heard is 2nd hand info.
Here are some of the connectors that Bombardier uses on the Fichts . . .
