Regardless whatever method you decide to use just go off of your factory under dash fuse box. Every fuse box will normally have extra slots open either for constant 12v power, accessory 12v power, or full 12v power. Just find out what fuse your accessory fuse slot is and get wire it out of there. Weather it be the ghetto way of just jamming a wire in there, pigtail fuse, or some kind of a connector.
