Yeah, the link you posted is what I found. I was thinking it would be easier to plug and play. What excited me was that when I put them into the shopping cart (to see shipping and tax info) I noticed that the diagrams were listed in my shopping cart for free - even with only the speaker harness and no speakers in the shopping cart. Could be a good deal $13.00 both the harness and crutchfield certified diagrams. I would have thought you would have to purchase the speakers to get the diagram, pretty cool that Crutchfield includes it.
