    this has (as the diagram shows battery leads. AFter I Installed this I found out that the battery is always engaged. How would I wire a 3 conductor jack that disconnects the battery unless a cord is plugged in? would I just run the negative of the battery to one of the terminals on a stereo jack ?

    a stereo jack but used as a cut off jack that disengages when you unplug your guitar

    most Tip Ring sleeve stereo jacks the ring connector will go to ground if you use a mono 1/4"plug , so you can use that ring connector to connect to your battery negative and when you plug in your cable the circuit is complete to engage the battery and when unplugged the connection is broken

    so the tip connection and the ground connection are wired as normal the battery negative is wired to the Ring connection so that it shorts to ground completing the circuit and activating the battery

    plug a jack into it you will see that when a jack is installed it will break the connection not add to it , so if you hooked your battery up to it , and you pull out the jack the battery will drain, but when you insert the jack there will be no contact to the battery and will not be effective, this is called a cut off jack.

    its the correct Idea just the wrong jack,
    plus if you look at that jack the switch is on the tip contact ,not the ground

    a stereo 1/4" jack will work fine for your purposes, and will make contact only when the jack is installed, that is what I use on my active pickup guitar and it works fine,
    just make sure the guitar is unplugged when you are not using it,
    you dont have to make it complicated

    24 is right, that jack is normally used to disable something (like a loud speaker) when something (like headphones) is plugged in.
