chtucker 11-01-2004, 09:20 PM A friend is installing a remote start on my new 5500.... What color/where is the wait to start wire? Also... I took a guess and thought that the medium duty wouldn't have a pats module.... it does? Howard Max Power 11-01-2004, 09:29 PM Wait to start wire will be blue at the back of the instrument cluster. GM's security system on these trucks is called Passlock II not pats. chtucker 11-01-2004, 10:01 PM Thanks... is the wait to start easy to find? Any idea which DEI bypass module I need? THANKS Howard Max Power 11-01-2004, 10:17 PM The wiat to start should be easy to find. It will test - when the light is on and + when it is off. I don't know if the medium duty truck will have passlock or not. I would assume not. If it does, any of the DEI modules designed to bypass Passlock II will work.
