Small Engines (Lawn Mowers, etc.): Wiring, kawasaki engine, engine model

Question
I have a late 90's model Scag 52. Model # SWM52/L Serial # 15251280.  I have replaced the 17hp kawasaki engine on it with a brand new 19hp kawasaki engine. My wiring is not matching up and I don't want to start cutting. I was needing some assistance bad because I have some cleanups to do this weekend. Let me know where you can help. Thankks.
