I am adding a (520T) Battery extender to my Viper 791 autostart and I need  some help.  The extender is made by DEI and I have figured everything out except one wire:

I dont know what wire on the viper 791 is the "(-) Instant trigger input"  any ideas?  The install instructions define the wire as follows:

"The (-) trigger output.  Connect this wire to the (-) instant trigger input of the security system.  This wire will send a (-) signal if the vehicle's battery is disconnected, triggering the security system"

Any ideas?  Thanks!
