you can't ... in fact one person on this forum triggered his airbag when he switched the wrong wires


there's no bypass you can do with the ignition wires because the anti- theft is done with a transponder and transmitter inside the key/pickup unit....dealer or good locksmith is needed

I've already taking the airbag off the steering wheel steering will start apart they say that you can bypass the system by crossing the yellow the orange wire with another one so you saying that's not true

If you are having problems with your Cadillac CTS not turning over when you turn your key then you can put a push button to activate the starter what you want to do is running wires from your switch out to the fuse block and find your starter relay and hooking to that when your car does not start from the key all you have to do is turn your key for Word in the Run position and reach over and push the button and it will turn up starter over in your car will start I had the exact same problem with mine and that's exactly what I did because it's way too expensive to put a new ignition switch in and have it programmed I bought everything for less than $50
