Re: Johnson
Boy, a wire harness for something that old is gonna be a trick to find, it's not like a starter or some other part that wears.
try Ebay, they have suprised me before, you may find a complete engine for cheap and then you would have other spare parts to boot.
Or just your good "old fashion" web search, i'm sure there are a ton of salvage yards out there.
Good Luck.
