you can do it a number of way. you can take it from the fuse box, which is the best way. use a key on power on key off power off so it comes on with the ignition.
good luck

one side goes to a body ground the other hot side i would use a fuse tap and go into a circuit that gets power when the car is on.
you can pull a fuse and then hook a voltmeter on the open connections to see what kinda voltage and when its active to that circuit.
