ok i have a 2000 gmc sierra, and my g/fs dad sold me this deluxe 500 bulldog security car starter alarm. i installed it with pretty much no problem, really time consuming, but i think i need some type of bypass module, and i dont know what one, where or how to get it. i cant contact the alarms technical support because they are NEVER open, any help would be greatly appreciated!!

 

get a directed electronics part # 555L it will allow remote start.Viper also the same part # .Try best buy. Trigger the module with a ground out when running from Bulldog unit, good luck. Also make sure the unit allows a second ignition outpput from the bulldog to the small gauge white wire in the column, this powers the pcm for the trans and must be powered before remote start or else the trans will go into limp mode and not function.
