Stereo & Electronics - Any rear power sources?

I am in the process of wiring my bottle heater and I am trying to figure out if there are any sources of power towards the hatch area. I was hoping to avoid having to run a wire all the way from the front for power if there was a wire I could tap into towards the rear. Thanks!

nope, you are going to need a strong 12 volt, like the cig wire. check the nitrous section
