Installing 2 units on a 2012 & 2016 Dodge Grand caravan, i am using guide #12971
1) do I need the relay when connecting the siren, can I just tie the siren +12v to the battery and use A4 - output to activate the siren, the way the horn does/
2) for an armed led i can use A5 ?
3) does the valet switch prevent the alarm from arming, or only prevent remote starting?
4) I want to use the EVO all as a starter and alarm so any programming steps I need to do would be helpful
i hope to get the 2 units next week but I am trying to get everything I need for programming, any guides would be appreciated.
