Type of power door lock

I have a 99 hyundai elantra. I just try to install a alarm/keyless system. I already found all other cables which need to be connected to the module, except the door loock cables. According to the installation guide of Rattler 310D, there are 8 common types of power door lock. 1) positive-triggered, relay-driven system; 2) negative-triggered, relay-driven system; 3) direct-wired, reversing-polarity system; 4) adding one or more after-market actuators; 5) electrically-activated vacuum; 6) one-wire system (cut to lock, ground to unlock); 7) positive (+) multiplex. Please tell me what power door lock type of 99 hyundai elantra, or, please tell me how to determine type of the door lock. Thank you very much.
