2016 Buick Regal Ignition Switch Wire

HELP! I Have A 2016 Buick Regal Turbo That I’m Trying To Connect A Kill Switch Relay To The Ignition Switch Wire. Problem Is That I Don’t Know Which Wire That Is For This Vehicle. Any Insights?:confused:

2016 likely doesn't have the wire you're looking for. The ignition isn't directly connected to the starter. The signal goes through the BCM.

Ok What’s About The Starter Wire?
Is Separated From The BCM Signal?

A 1-month subscription to a service such as AllData DIY will get you access to all the factory service information, including the schematics you would need to decipher the wiring to selectively disable the vehicle.
