05 buick rainier remote start wiring

the 791 module is a by pass for the passlock 2 system> now im not sure what a GMBP is.I guess I will look for it on e-bay  I was to the understanding that this was i simple install as other post say, as well as it only taking 30 mins ?  Thank you for the reply. 

I finally was able to get through to tech support at alert. There 791  by pass module for the pass lock 2 system instructs you to connect the yellow wire to (+) positive voltage. what they didnt say was that both wires have voltage.  one has high voltage the other is low voltage and the low was the wire I need .when i moved this wire the the system worked ! hope this helps anyone else that may run into this problem . 

also if you do use the 791 pass lock bypass module and it has a red LED.When the module has learned the key resistance the red LED should go out . If it stays on it did not read the resistance . Hope this will help someone else.
