programming new remote control for 96 Impala SS

Looking for information on how i can program a new alarm remote bought from dealer. I can have the dealer do it for about $60...but like most problems i've had and fixed with this vehicle, i'd like to learn by doing. Any advice will be very helpful.

There is a breakout connector in the trunk, along the left quarterpanel lip.

1) Open the driver's door window to prevent unintended lockout;
2) Locate the breakout connector in the trunk;
3) Jumper the two pins. The doors should lock then unlock;
4) Press any button on the remote. The locks should lock, then unlock. Program ALL remotes at this time.
5) Remove jumper wire, and test the function of remotes.
