    791 bypass module wiring

    Installing a remote starter in my 2002 trailblazer, I put the bypass GM-9 Harness in and would like to know about putting the 791 bypass module in. I all ready got the wire hooked up except the blue one which i am having trouble finding out where it goes. They are pretty vague about the passlock II system. Can any one help me?
