no, i tried factory arm/disarm wire but Ground pulse on that wire is not a clean ground, it has resistance on it.

Go to the factory doorlock motor wire-----that is, the wire that goes to the doorlock actuator itself-----on nearly all cars, it'll be a strong positive when you lock the doors.
Then use a relay to invert that positive to a ground.
85 and 87: ground
86: factory doorlock motor wire
30: this will now show a ground every time you operate the locks.
