does mazda 6 have any more factory alarm then the imoblizer system for the key ??
Yes it has a factory alarm.
The immobilizer for the key is NOT an actually an alarm..it is an immobilzer (does not allow the vehicle to start without the proper key code read at the ignition switch antenna) and the Mazda 6 has that as well.

      Yeah..you are new to this..but hey..we all started somewhere. Let us know the year of the mazda 6 and we will post a diagram for you. 
Hows that for service?
I have a slight concern about 2 things...1) you got it on ebay...and 2) it's a brand I never heard of..and I have been in the business for over 15 years.
But whatever..we will walk you through it..don't worry

think that omega or something makes them. 
Thanks for the help so far !
      also need the year of  your vehicle as there may be some difference in the electrical systems from one year to another.

My source only lists a mazda 6 for that year..doesn't specify if wagon or euro version but see if this helps anyhow....good luck. If you need further help on how to do the door lock setup let me know and I'll send a diagram.
The doors lock and unlock through the same wire. To lock you will use a resistor to ground with a relay..to unlock you use another relay but send a ground direct.
