ranger 12b/2 car alarm

Hi,My used car has the above alarm installed.I wonder if anyone could help me find the installation manual of this alarm?I am trying to get the doors to lock and unlock with the alarm.I have the wiring for my car.Thank you very much.PS: Sorry for my English but this is not my mother language.

I assume that it is a little bit difficult to find the installation manual.So, could someone tell me how to identify the signals that my alarmproduce, using a multimeter?I have done that already, measuring the voltage to the ground at each wire, but I can not come to a conclusion which wires is for the doors.I am sure for the power supply wires and for the turn signals but I don't know what the others are.Thank you again.Nik
