Toyota Avanza / Daihatsu Xenia

Does anyone have a wiring diagram for the Toyota Avanza /Daihatsu Xenia 2014, y have a problem connecting the centralized door locks to the after market alarm, I found 2 wires that are set to ground and when push the drivers lock open one of the wires show a positive pulse for a moment and  the other wire stay in ground and viceversa when push the door lock to close, I set 2 relays to send a positive pulse to each wire, but doesn't work and the wires start to heat, does anyone know how to connect them properly 

Thanks for your time and support
