Need help on wiring

I'm doing a engine swap from a Kawasaki FC420V to a 17.5HP Briggs. I need a wiring diagram to change the wiring from KW to Briggs. The mower has a regulator and is a 2 wire alt. Briggs is a 1 wire alt. Any help would be appreciated.
This motor is on a Snapper SPE140KW Walk Behind Mower with electric PTO.
