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!!

 

go to oreily and get the passlock2 bypass module

 

I have a new Crimestopper GM-SL bypass module that I will sell if you are interested. I am using the same one in my truck and it works great. I will sell it for $35+shipping.
