Congrats on the new radio!
The 6 disk and the 1 disk headunits both had the amp I think. So, if you get one of these (NHParrot sent me this link a while back)

Although, it looks like there isn't one from toyota to alpine.

I'm sure somewhere out there one is being made by some other company. Where are you getting your wiring? I'm sure they'll have something along those lines.
You might (this is what I did) is get one of these

And some of those things (I forget what they're called) and connect the wires manually (where you slide in the wire and then crimp down on 'em).
As for the pockets, I don't even know what kind I got.

It was some no-name brand. The one I got though came with an assortment of faces, so I could pick the one that would be flush with the dash.
