Constant 12 volt in cab

Looking for 12 volt power always on inside the cab. I don't want to go to the battery.
Thanks in advance.

You can also use an add-a-fuse to the fuse panel in the passenger foot well. That's what I've used for several accessories.

Interesting; I too thought they were on a timer.

Might be worth doing an overnight experiment.

It’s also possible that the previous owner disabled the time-out using FORscan (see spreadsheet line 63).

Safe travels,
