I have a Ungo SR6000 and i want to add a scanner to it. i know how to hook the scanner up so that it goes on when the cars off but i want the scanner to go on with the alarm is armed. The shop i got it installed at cant do it and i dont have the install manual so im stumped. All i need to know is what wire the (ground when alarm is on) is. or how to figure out which one it is.
