If the car has been running upon cutting the car off the accessory outlet remains energized for a lengthy period of time (30 mins or more) it eventually cuts off.
On the other hand. Once off...if the radio is powered on...the circuit cuts on...cut radio off circuit cuts off. You can cut radio on and off without keys by pressing on button.
I want my device I use for work to come on and off with the switch but not to cut off an hour later.
Fuse 23 shows as delayed accessory I may have to see if this operates the way I need it to.
