Mazda6 2011, 2.2 Diesel Central Locking Question

Hello Guys,
I have installed smart keyless entry and start button to my Mazda 6. The problem now is that I cannot figure out how to connect both lock/unlock signal wire from the system to my car. I have spent last weekend just trying to find out the open/close wires and I tried connecting each pin from the door lock and latch with negative but got nothing. With the new system that I installed, it is a negative trigger and I think my car is as well. I found some wiring diagram on the internet but couldn’t get benefit from it. I would really appreciate your help and any suggestions.
Thanks in advance!
Kam
