I know that the blue plug that you have talked about before was for the parking light. I speak about blue plug connector (F) for door trigger because I have found a wiring diagram at the bulldog security website and this wiring diagram said:  "DOOR TRIGGER  BLUE (-) N.C.   @ BCM, (BLUE, 24-PIN PLUG(F), PIN G"

It work but only if I don't use diode, I don't understand why... Now all is working, remote starter, door lock/unlock & alarm system. Thank you very much for your help. Now I will do a tutorial for remote starter installation in 2010 Mazda 3.

you need the diodes or you will have backfeed onto your BCM.

the bcm has negative inputs, if you sent 12v to it, you will smoke the bcm. make sure you have the diodes the correct way.

I have put diodes for the door trigger and it is working. I suppose that I have to put a diode on the (-) 2nd starter wire used to activated the clutch bypass relay and put the cathode side on the relay side?

when i do clutch bypasses, i dont use diodes. the unit themselves have diodes to prevent backfeed, but if using a relay, its not necessary.

you can put one across the coils to prevent voltage spike, but its not necessary for your application
