Without OnStar, without Monsoon.

I want to install an aftermarket deck. I know there's a wiring harness adapter that retains the chimes. I know you lose the calendar function with an aftermarket deck.

What if you don't care for the chimes, what wiring harness could you use instead?

I change cars too often to put one here.

Metra 70-2003 You will have to connect the red wire of your deck to the red wire that comes with the harness. Connect the other end of that red wire to a fuse in the fuse box that gets power only when the ignition switch is turned on.
