2007 Saturn Ion, door locks, button

I am looking specifically for the 'connector end view' for the door lock button in the 2007 Ion.

The button has 4 wires going to it and I would like to know what the colors are and what the assigned task for each wire is please.

My modification that I am doing is adding a lock button to my car. It has power door locks but didn't come with the door button. It's a GM thing. So I have been running a button from a 2005 Cobalt and the wires connected to the button and the BCM without a hitch but I wanted something newer and ordered the Ion button. The problem is that the Ion has a 4 wire harness and the Cobalt version was a 3 wire. Hence my problem now.

So if I may request someone to take a peek into the Saturn world and tell me what the 4 wires do that go to the Ion door lock connector.

Thanks!

As it turns out, the Cobalt one is and the Ion isn't. Late yesterday I was provided the pin outs for the 07 Ion connector. Of the 4 pins in the button, only 2 are used and these are the white and ground.

These are really all I needed to make this work as planned but it would have been nice to have it lighted. But thinking about it, how many times in the dark do I need to unlock the door?
