Part of the door lock harness in built into the main harness that runs in the car. I would buy the harness the plugs into the back of the door lock switches. From there I would make my own harness. I will try to post a pic of the factory wiring. Just make the same harness and it should work.

The diagram is here. Print it. I would run at least 12 guage wire with good jacket

That would be the way to go,

Here is a schematic

As you can see the part that is inside the car is only 3 wires plus a run to the fuse block

I would get the locks working and then worry about the security system or don't even connect to the security system

That refers to the stock 81 Theft Deterant system. If oyu try to unlock the doors from the inside with the door locked by the key,, the alarm will sound.
