I need to find wires to tap into at BCM. Wiring diagram references the BCM diagram (Crimestopper). Its gives pigtail and pin out locations

You can always use a meter to verify wires? If you unplug one of the connectors and see a dark blue wire in pin 8 and a dark blue/white wire in pin 1, I would say that's a good chance at being accurate. Not sure how a diagram is going to comfort you any further. And if the dark blue/white has a light blue (park lights) next to it, and the dark blue is next to a black wire (trunk release) then that should narrow it down a little further.

A. You don't need a BCM diagram. You do plan to TEST each wire before connecting to it, right?
B. Besides, going to the BCM in those cars is awkward, inconvenient, and unnecessary.
As the Impala sells in greater numbers than the Monte Carlo, use the search feature here for the Impala. Door trigger, doorlocks, trunk release, and parking lights can be found in other, much easier locations in the car. Also, when you get the parking lights at the switch, you don't have to bother with that relay-isolation nonsense.

What about using crimestopper's GM-SL data interface module? Is this a  one wire hook up to the purple wire on the OBD2 connector? Can this module do trunk, doors, passlock, parking lights, turn on your defroster? Very easy to hook up or not?

If you read through the installation manual for the GM-SL it shows that it will control door locks, trunk, passlock and parking lights. It also shows that it will not do defroster for that car.
