which colored wire can I cut to disable passlock permanently? on 2005 Chevrolet Colorado

Several people on forums have done this with success. They cut blue and white striped wire, located in plug harness under dash, towards drivers door. Truck will not start for 10 minutes 2 or three times a week. I know little light will stay on in dash, but thats ok. No problem of theft. I want to do away with it. Thanks Bill
