put the above wires too.... the pioneer connections...

 

Why not buy a Scosche car stereo connector from Future Shop as well? It plugs into the factory harness and hooks up to the Pioneer deck. It gives the wire colour codes on the back of the package. Will make your life easier.

It is part # GM02B (1988 and up GM)

Here is a pic (on the left)

It doesn't matter which ones you hook up first as long as the deck is not plugged in at the time.
My own personal way of doing it is ground, constant, accessory, illumination, power antenna, then speakers. Once it's all done, I test it. If it's good, then I secure the wires into a nice neat line, plug in the antenna, rca's and tuck them away into a safe spot in the dash.
