I hardwired a couple accessories in (radar detector and dash cam) I found there was only about 5 fuses in the interior fuse box(passenger foot well) that cycles with the ignition. I ended up using a add a circuit on fuse #33 (which is listed as a spare on my car) and my stuff comes on and off with the car.

As well If i remeber correctly the fuses directly above and below 33 are also switched but have something already assigned to them so the spare is obviously the best choice.

Depending on year your results might vary so identify it with a meter first to double check.
