Have a couple 2018 Chrysler 300's new to our fleet. I am trying to hook up our vehicle tracker, a Garmin GPS and dash cam. I need to have a fuse that is only on when the vehicle is running and off when the vehicle is off.

It used to be a safe bet to put it to the radio fuse, But that's not the case with these new cars, Things don't power on until x minutes after, power on for only x minutes then shut off, stay powered for x minutes after the car is shut off. it's all a big cluster f* roll the dice to find the right one. I really just need a simple fuse x turns on when the acc is on and off when the car is shut down..
