adding power door locks to 99 cavalier

Hello,

I have a 99 Cavalier that doesnt have power anything. Recently I had an avital 2100 alarm installed, that supports power door locks and would like to add an actuator to all 4 doors. Having this done where the alarm was installed would cost me around $200, but based on the prices I've been looking at, it seems I can do it myself for under $50. This is what I would like to be able to do, when I push the button to activate the alarm, I want all doors to lock, when I deactivate, all doors to unlock. According to the 2100 installation manual, I need 2 relays for this. I've read a few articles online, on how to add the actuators to the doors, wiring diagrams, etc.., but on the cars I have seen it done, they usually have a wiring sleeve that passes the wires from the door to the car. I would need to double check, but since this car never had power windows or door locks, I am 99% sure it doesnt have a way to do this. So how would I go about running the wires? I assume I would need to drill a hole, but then how do I keep the wires from getting smashed everytime the door closes.

I would also like to add 4 rocker switches to the center console so I can open/close each door individually from the inside. I am not 100% sure how I would go about doing this, any suggestions would be appreciated.

Thank you

they make contact when the door is closed.

I was just out there taking a look at it, and I just realized, the front doors have speakers in them, of course I have a wiring sleeve. So that takes care of the front, on the back doors the holes to run wires are already there, so I think all I need to do is run some split loom tubing from the doors to the car and I'm set.  

I decided on buying the power door lock kit from bulldog security, along with the trunk release kit. It says one is master and 3 are slaves, will this stop me from being able to control each invidual door later on? I'm looking at this wiring diagram, which I assume is pretty much the same as bulldogs http://www.partsexpress.com/pdf/330-013.pdf and trying to think of how to add switches to that to control the doors from inside the car. How do these actuators actuall work? If I hooked one up directly to 12v and ground it, would it open or close and then reversing the polarity would do the opposite? If so, then could I just wire up 4 DPDT switches, add 12v to them, and hook them directly to the actuators? Along with the wires that connect to the relay included in the kit.
