Exclamation Hard wire head unit

Has anyone out there tapped into the factory radio wire harness to connect their head units. I am thinking of just doing that and bypassing all the BS associated with adapters etc etc. Any help would be great, I already have the color diagram for the wires.

Just follow that and solder the wires it tells you to. And it should be cake.
