Premier Elite 64W wiring an alert led

[nong]

Hi

I would like to attach and program an LED to illuminate on the 64W when it is armed. It seems I can wire the LED to the Digicom outputs 1 - 8 . Forgive the silly question but where would I connect the ground? Would it be the "DC -" connection on the same connection block as the outputs ?

Thanks
