need info for 2003 yukon tach and location of wire . and bypass passlock for remote start without module
just goto a coil, its the wire thats a diffrent color than whats in another coil so say in coil one its pink, black, grey and red and coil 2 is pink, green, grey and red - its the green or black wire. The coils are lined alont the side of the engine and have the spark plug wired coming off them, there is one for each cylinder. I would advise to just get a moudle, you can get one from bypasskit.com that plugs into the data bus. to do your locks you'll have to get a data interferance kit, also plugs into your data wire - pin 2(viloet) of your OBD2 plug
