what i did was splice into the acc line in the ignition harness, ground it out to the headlight groud (there is a grounding spot up there), and then run the wire under the rubber on the door jam and the a-pillar thing, up on the top of the windshield. i lost the thing that held it on the windshield, so i stick it in the elastic belt thing that is on the cd holder on my visor. always works good for me! and its easy to take down, and you can just tuck the wire up the the headliner on the top of the windsheild...
so it goes off every with no key, and on when i start my car~!
