Ignition Switch
WARNING: This page is about a different car, the 2018 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The ignition switch is installed in the instrument panel center carrier and is hardwired to the Body Control Module/Gateway Module (BCM/GWM) assembly. When the ignition switch is operated two signal wires from the BCM/GWM assembly are connected to ground.
