    I have an electrical draw even with my audio system turned off. It is enough to kill the battery in 10 hrs. I removed the 30 amp fuse and have had no problems. If I install the fuse it happens again. Any idea what or how the draw is occurring? I have considered installing an aftermarket system and hard wiring it in with its own circuit breaker. I should note that this is not a constant problem as sometimes it will go for a couple of weeks and then start again. It is really frustrating!! Thanks

    I’m looking for 12vdc constant power source for an aftermarket stereo install on a 2007 Toyota Tundra 4×4 4.7L. Only solution I’ve come up with is to run a new wire from the battery.

    Car Radio Battery Constant 12v+ Wire: Red or Red/Green
    Car Radio Accessory Switched 12v+ Wire: Gray

    This Is the info i keep finding but the only red wire is a rear speaker wire. I do have a bluish green wire in question but there’s no voltage on it.

    Duane, run a primary wire to your steering column and tap the white wire in your ignition switch harness. This white wire will provide you with a constant power source. Hope this helps. Good luck with your 2007 Toyota Tundra.
