How hard would it be and would I only need this one kit?
https://cgi.ebay.com/dll?ViewItem&item=3000364998&category=14934
Or would I need something else? Also how would I go about making the kit work with my Viper 300ESP alarm. Thanks!
I finally want to take advantage of having an alarm and actually unlocking my doors when I disarm my alarm. No switch is needed, I'm only gonna use the remote to lock/unlock the doors. Thanks!
This kit would suffice for the installation that you want done. After you get the kit you will need to hook up the relay pack like this diagram:

You will only have the two relays included in this auction and have the output of the Viper alarm attached to 86 pin of the first relay and 85 of the second relay. Then you will need to atach all the common colors from the actuators to the respected relay output ( PIN 30 ) for lock or unlock.

Ok mztykal,
I have done exactly what you are talking about on a 2k neon, and it wasnt that hard just the wiring through the doors was hard, and youll have to go to a junk yard to get the rubber boots for the rear doors as yours probably dosent have them, make sure and get the little plastic thing that clips in the wiring boot to the door pillar. but i would buy this kit https://cgi.ebay.com/dll?ViewItem&item=2906981180&category=1467 It is the kit that i installed and it works well with a keyless entry system, there are two wires coming out of the harness that connect to the lock and unlock output on your alarm as long as thery are neg output. well have fun and take yourtims bending the lock rods that is the hardest par, cause of the angle youll have to have on them.
