Both of our parts lookups do not show a Smart Spark/S.A.M. module, what makes you think that his engine does???
Is it possible that he is putting up an incorrect model/spec number?????? Well yes.........
Is it possible that both of the Kohler parts lookups we put up are incorrect??????? WWWWEELLLLLLL yes.
This poster might have a hideous "Frankenmower" that he has not told us the full story about.... YES!!!
To the O.P., why did you replace the harness as you said you did in the first post.
Can you tell us the full story, and give us a clue as why your model/spec numbers are notjivving with your thread?
Can you put up pics of what you have, and what you had?
