I have a kohler CH20QS 20 hp engine that I am putting in my Max IV and I am not sure where the wires from the engine connection go. It has a 5 prong plug that has one prong that goes to a white wire, one goes to a green wire, one has a red and blue together, one has a red and purple together, the last one is empty. I have looked at diagrams but they are kind of hard to understand and don't really give enough info. I am hoping some one has this engine and can help me figure out how to wire it up. Any info would be MUCH appreciated!! THANKS!!!
