I purchased 2 wiring harness from Porch Electric for my F-Cubs, both quality made. You might give Eric a call and see what he can do for a local, IL guy, they are great to deal with. Also, if you can't get responses from Mike, give Bob a call at Hamilton Bob's, he specializes in number series Cubs but is getting into Cadet parts. I recently purchased a harness for my CC 73, I have not installed it yet but appears to be equal quality to Porch's and was a little less (comes with a diagram and labeled wiring). He doesn't have all his new stuff listed on his site so you will need to ask.
