carvox king eagle 2005 dodge dakota

i got the carvox king eagle professionaly installed in my 2005 dodge dakota and everything works except the starter, i noticed that there was a wiring harness left in my box meaning it wasnt installed, the wire im worried about is (ground when armed output to starter kill) do i need to have this installed or is it out for a reason

thanks, steve

He did not hook up your starter kill relay.  This is not a must have but is nice when your truck is armed the starter wire is defeated so someone could not start your car.  Alse this can be an anti-grind relay, when vehicle is remote started and you get in and turn your key too far you wont grind the starter. 

Good luck with the carvox, I have had three quit working in cold weather.  Had to replace with different systems.  the internal relays are not made for the cold weather that we have in MN.
