I'm hooking up an audio system in my car off of my stock HU, so i have everything i need except the remote wire. I'm not running a wire and messing with the harness and all that for the radio, so i decided to use a fuse in my rear fuse box. (My battery and rear fuse box are under the back seat)

I need a fuse that is on when the key is on ACCESSORY, but off when the key is off. I've tried TONS of these fuses and i couldnt find any. ALL OF THE FUSES i tried are *always* on. Power windows, power seats, Cigarette lighter, turn signals, instrument panel, stereo, all of them.

The closest thing to my goal i found is using IGN 3 (Ignition #3), but obviously that only goes on with the engine. Im using that now, but i would prefer a fuse that actually turns off with the car. If the fuse is on, the amplifiers turn on and will drain my battery.

Anyways, anybody know of a fuse that will accomplish this? Im probably going to go through each and every fuse/maxi-fuse. Im sure one must be off that isnt ignition related...
