03 grand am locks

I'm planning to install a remote starter-trying to become familiar with the power locks setup before I begin.I understand the one wire & 1.5K resistor concept but I would like to have priority drivers door unlock.Is this done through the same wire via the body control module (double pulse) or is there another connection? A schematic would be nice!  Thanks.~~~grsmnky~~~

Drivers door lock wire is slammed down in the drivers kick. It's tan reverse polarity. Trigger this wire with 1st unlock with a relay. Second unlock will be on the other wires you have listed.
