Turn off 12V cigarette lighter when engine is off?

[laramie4x4]

The cigar lighter on top of my dash has a battery symbol on it, and it is always on even when the engine is off. Is there a way to make it only on when the engine is running? Don't want to drain the battery if I forgot to unplug.

Here’s another thread of this where you’ll find the answer.

I just did this 30 mins ago on my 2025 RAM 1500 Tradesman. Interior 20a fuse F54 from the factory is positioned on left and middle in the box, which is always powered. Pull the fuse and move over to middle and right, which is accessory. Takes 5 mins, including pulling the panel to get to fuse box. Cheers!
