Got the alarm wired in, I went with the remote on/off key fob like you suggested. I was wondering if the remote relay was going to draw the battery down overnight, so I first tuned it on and left it set for 24 hours. It cranked over like crazy yet so that was not an issue. Here's a video of it in action, its pretty quiet so turn your volume up.
