    wire it up to an ignition fed 12v source so its only active when the ignition is on

    if u wired it direct to battery it would be live all the time and over time, it would drain the batttery!

    Wire it up to any ignition feed to come on when you start the car.
    If you wire it from the battery it will be on all the time not a problem if you want it like that just make sure you use a fuse in the circuit.

    the black will be ground, the red will be permenant live and the third will be switched live.

    black to a ground point/ - battery terminal

    red to + battery terminal

    3rd can be to ignition or have it go straight to the + battery terminal but wit a switch in-line so u can turn it on/off as and when u want to use it
