pull the fuse. I dont remember what one it is, but you should be able to find it on here from someone. the other thing you can do is find the fuse, use two fuse taps, some wire, an in line fuse holder and a two position switch and make a "dome light over-ride" switch. costs about $12 and works awesome.
