I would plug it into the outdoor light, hit the switch an hour before I was ready to leave, the car was toasty warm when I started it. I would also say replace the battery, it just IMO not going to last. Lighter oil is a must. Just don't forget to unplug before you leave. I only did that once...
does that just install into the lower radiator hose? they actually sell those at my local napa
