Hard wire it directly to the fuse box in your car (to a fuse connection that runs even when the the car ignition is off, if you prefer) using a separate flat wire that terminates with a female car lighter plug ( available from any Radio Shack, etc). Run the wire under the carpet or seats to exactly where the unit needs to be placed. Then plug the Auto Cloaker directly in right there with it's supplied male lighter, making it easy to remove to another vehicle if and when needed.

Two options:

1) If the location is permanent, forget the female end of the new wire; just snip the ends of the supplied male plug and connect it directly to the fuse box.

2) In addition to the above, you can install a simple switch in-line such that you can turn it on and off any time you want. Again, any single pole 12 volt switch (rocker or push button, etc) would work great and give you total use flexability. All this is pretty easy, low cost, and also fairly quick to do, giving you maximum ease-of-use and a perfect location-guaranteed application.
