    Let me search some more and see what I have. The attached is for a 3.0, but I am not sure it isn't the same for all Merc's. I'll check and hopefully Jim or someone will have the book to double check.

    That's it for main motor harness and to the dash. The colors are the same for all Mercruisers. The EFI harnesses have a list of their own. Does that answer your question or do you need more info?
