If it's hooked up at the under hood fuse box positive terminal, moving that to the batt + is something you should do like yesterday. I fried a VW Jetta that way and ended up scrapping the car, rewiring everything was just too much work.
Also, you have a Saturn, like me. Just be aware that the paneling is plastic, not metal. It tends to crack if it becomes warped. Especially when it's exposed to below freezing temps. Not saying it'll happen, but it's a possibility.
