Stereo & Electronics - How to make it so 12V adapter only has power when key is turned?

Hey I was just wondering if there was a way to rewire the 12V adapter so that it doesnt have power to it when the car is off? That way when the key is in the accessory position, whatevers plugged in to the outlet will turn on, and will turn off when i shut the car off. I ask cause its kind of a nuisance to have to turn the thing on and off seperately.

I guess you could cut the +12V wire going to the lighter and splice one in coming from the driver's side fuse panel that's switched 12V power (check your owners manual if you aren't sure what I'm talking about - it'll be under something like wiring in aftermarket accessories).

That fuse panel has three empty slots in it that will accept spade plugs - one source is 12V hot all the time, one is 12V switched (what you are looking for), and one is 12V retained accessory power (like your radio has - it will only turn off after the door opens).

You could also wire up a new socket that taps into the extra accessory spot in the fuse panel. If I remember correctly there is a spot where you can add your own fuse to tap into different sources of power for the purpose of adding extra circuits (power all the time, accessory, ignition, etc) That way the stock sockets will maintain full power all the time just in case you still need it at some point. I sometimes leave my cell phone in the car to charge. Actually since there are two power sockets next to each other, you can wire one to that accessory port and leave the other the default way.

Apparently theres some large black wire near the 12V, a little below the stereo head unit, that i can tap into? Not sure what it runs to but a friend with a formula suggested I try that wire.

Near the fuse panel there is a pink wire, get a volt meter and double check, but on my car one of the pink wires were the key on power, thats how I wired up my electric water pump.

Actually there are many pink wires, just start checking to find whitch ones are key on. Good luck
