Viper Alarm

I installed a viper 550 esp alarm into my truck a few weeks ago.  I hooked up most of the wires, but I didn't connect the brake wire because I didn't want it to shut off when I press the brake without the key in.  I had assumed that if my alarm was triggered, it would shut off the truck.  I tested it out the other day, and even the the alarm triggered, and the siren going, my truck stays started.  Is there anyway I could use an alarm output, such as the + to the siren, to turn off my remote start?  I was thinking of attaching the siren + to the brake shutdown wire.  I am reluctant to try it though because I figure it will significantly reduce how loud the siren is.  Is there any other output that occurs when the alarm triggers that I could use to shutdown the remote start?

You could use the domelight supervision (-) output that triggers with the alarm and flashes the interior lights. You would have to wire it to a relay to get a (+)  output to connect to the brake shutdown wire(+) input. The only drawback is the remote start will also shutdown everytime you disarm the alarm since the dome supervision is activated upon disarm. Good luck.

"ask the exact same Q to do the exact same thing, with something else !! "

Reinvent the wheel?  Maybe you didn't understand the question.  I want something to shutdown the car when the ALARM is triggered, not when the brake is pushed.  I have it set up to shut off the remote start when I release the parking brake.  It's just my personal preference.

Not to confuse anyone:

12V is 12V - whether it comes from an O/P out of the alrm unit, the battery terminal or the brake switch.

You could, but easier just to connect the brake switch connection & the siren O/P both through diodes into the remote start turn-off.

<<<<Just use the siren O/P to the brake switch input - use diodes to isolate the siren when the brake pedal is pushed>>>>

I'm glad U re-posted the correct answer

That would be to simple......
