Viper problem in 2006 Sierra

The green wire on the 457g goes to the green neg door trigger wire onthe viper.

I unplugged the wire going to the gray/black in the black plug for the domelight. Door trigger works perfect.  Still gettinbg the siren going off when I hit the brake pedal.  I have reprogrammed the 457 module 5 times so far.  Even if I unplug the wire from the Viper to the white wire above the brake pedal, I still get the siren going off.  AAAAAAAAAAAHHHHHHHHHHH

It sounds like you have the brake wire going to the siren wire instead of the brake wire on the viper. The brake brown wire is thinner and in a plug with a grey,WHITE/ blk, PURPLE / white and blue/white wires. 

I triple cjecked the wiring, I have the thicker brown wire from the large harness of the Viper going to the siren, and the thinner brown wire from the viper going to the brake.  I inplugged the brake wire and I still get the siren going off, the lights flash and the door locks lock. Like the alarm is getting triggered some how.

If I unplug the 457g unit, it still does it. Think I got a bad alarm brain?

if you dont have the brake wire hooked up it makes no sense why that would trigger the alarm. Is the alarm armed when it does this or does it not mater. The only thing I can think of is maybe a bad ground sometimes the will do wierd things when the ground is not good.
