According to your information above ( without giving the make, model or year of the vehicle ) all you need to do is hook up the following:

    • Door Lock ][ORANGE / White --------------- BLUE wire on the H2 plug
    • Door Unlock ][Pink/Purple --------------- GREEN wire on the H2 plug

    your vehicle has a posititve pulse door lock system.  If you keyless entry unit gives you a negitive pulse you need to use two relays to make it work.  First run your lock wire to the first relay on pin 85. Then run pins 87 on both relays and pins 86 on both relays to a fused 12 volt source.(5 amps) Run your unlock wire to pin 85 on the other relay.  Then the pin 30  from each relay will go to the wire in the vehicle door lock system. (the relay that got the lock will go to the lock wire and so on.

    Actually the viper alarms have both a pos and a neg output ( check in the owners manual ).  The wires first supply a ground and then suplly a +12v.   All you would have to use is the blue for lock  ( blue is neg unlock and pos lock ) and the green for unlock ( green is neg lock  and pos unlock).  That alarm should have a small three pin plug with the middle pin empty.  These wires are a low level output but should still operate the locks.

    Just double checked and my spare 500esp  ( I have that alarm too) and it says right on the back that there are two ouputs for each door lock wire.  You don't have to program anything just hook it up like i said above.

    auex- so all i have to do it connect my output wires (BLUE AND GREEN) to the right wires within the car? (UNLOCK /LOCK)? its that easy? i thought i needed a relay, because the module wouldnt have sufficient power to do so? have you wired it up using only the blue/green wires before? has it caused problems? thanks
