I have a toro whreel horse 210-5 and it had a b/s 10 hp engine with a broken valve, so I removed the engine. After removing the engine, I installed an engine from a john deere 160 lawn tractor. The engine is a fb460 kawasaki. I left the wiring attached to the kawasaki engine and installed the kawasaki and wiring on the toro wheel horse.Everything bolted up and fit in ok. But! when I turn the key on. nothing happens. not even a click. I'm sure it is the neutral switch on the toro wheel horse. I took some pictures to explain what I am talking about. I need to know if someone out there knows how to wire up the purple wire and the yellow wire from the neutral swiitch, to the new power takeoff and relay. I put the old wiring from the toro wheel horse and laid it on the top of the kawasaki motor and tied the purple wire and yellow wire to the original way it was on the old wiring so you would know where they went on the pto and relay switch. the new installed pto has different colored wiring which confuses me. And there is no relay switch on the new wiring that is installed.
