I have a grasshopper 727k2. It had a Kohler CH740 engine. Had a fire and replaced with Kohler CH742. My problem is that the fire destroyed electrical connector between engine and mower. The wires coming from the new engine white, green, purple and red. The wires coming from the mower to the connector are red, yellow, black and purple. I can find no info as to which wires to match. I am also a newbe to the forum. Thanks for any help.
