Shawk writes "I was successfully able to install a relay and use the wireless charger wire as a trigger. If you don’t have a wireless charger you should still be able to tap into the ignition on pin in the ecu harness, it’s shown pretty well in the mazda3 charger install. If anyone wants a picture let me know I just forgot to take one. There is a open spot under the driver side dash where you can put a bolt through and mount the relay, visible in picture. Now my radar and dash cam both turn off with the ignition off. Happy to help anyone else through the process or go into more detail. "

If you are using the wireless charger wire as relay trigger then why not just take power off an always on tap [like accessory fuse] ? When you start tapping ECM wires i would get nervous,
