chevy bypass GM-SL

I am using this moduleand on connector 1 there is a gray/black input wire for the dome light supervision wire in the vehicle

the vehicle is a 2005 avalanche, I connected these wires together

On connector 2  there is a white wire (-)output door trigger, and I have connected this wire to the green wire on a clifford alarm/remote start

Now when I arm the vehicle with the clifford remote, about 30 seconds later the aftermarket alarm false and triggers the siren

Anyone know what this could be

Thanks Mike
