Currently looking to install a Viper 4105 in my 2009 Ford Escape. There are two wires on the remote start harness that show they should be connected to a "(+) (30A) HIGH CURRENT 12V INPUT". Should that wire be a 12V constant, or should it only supply 12V when the ignition is in the run or on position?

Thanks in advance.

Must be constant. This constant power allows the system to be ON awaiting commands from the Viper 4105 remotes.
