'04 mazda 6, you must use relays’?

because most alarm/remote start modules use a transistor output for lock and unlock and that is not a strong enough pulse to make things work, thats why you need to use relays to provide a strong enough ground pulse.Mike Battaglia

i beleive you can use  a 1.5 what you can do is just tap the ground resistor to the wire and find out if it unlocks it.  also another reason for the relay is most alarms use unlock/lock wire that switch polarity so that would also cause conflicts if they are on the same wire.

i just checked the audiovox wire info and it does say to use a 1.5k resistor, and i would do what jmaxx just said and tap the wire to a good ground with the resistor and make sure it works, thats what i always do.
