04 mazda 3 power door lock

i am install the carvox cx2300a alarm with remote starter on mazda 3 04 model the power lock wire is GREEN/ red (-) but the alarm module central lock wire only said door lock wire doesn't said (-)or(+) how do I know which one is which..any ideal Thanks!

Almost all systems use negative pulse outputs to control door locking and unlocking. Your 04 Mazda 3 requires a negative pulse through a 1K ohm resistor to lock and a straight negative to unlock. However, if memory serves me right, you can just use the factory alarm arm and disarm wires and these will lock and unlock the doors as well. I might be wrong, but to test it, find your arm and disarm wires (BLACK/ blue and BLACK/ white in the driver's kick panel...harness going into the door) and pulse each with ground, it may require two pulses to unlock the doors. I might be wrong but I kind of remember not having to use a resistor on the Mazda 3. Update: I just read the installation manual for your system here. Your system appears to have internal relays for door locks. If you look at page 26 you would follow the diagram for "Multiplex Negative Return Circuit" with a 1K resistor inline for lock and no resistor for ground. But again I think you can use the arm/disarm wires instead of the resistor. On another note...taking a look at the manual does not instill a whole lot of confidence in the quality of that system.Installer, IT support, and FFL. I need less hobbies.

yes i try the factory arm and disarm it will lock and unlock the door so is that mean i don't have the connect the power door lock just use the factor arm and disarm wire for lock and unlock the door right?

Yes, just connect the negative trigger lock and unlock wires to the arm and disarm wires! Works for me!commit your way to jehovah and he will act in your behalf. psalms 37:5

if i use Multiplex Negative Return Circuit do i just take the lock wire thru a 1k resistor and unlock to car body ground???

Unlock connected directly, you may need to use a relay to supply the ground via the resistor, as the on board resistance may hinder it from functioning!commit your way to jehovah and he will act in your behalf. psalms 37:5
