I completed this DIY over the weekend but ran into a little problem. My detector stays on all the time as opposed to turning off with the rest of the car. I tried slots 5 and 20 (cig lighter) but got the same results. Slot 7 wouln't work b/c a pice of plastic was blocking the fuse tap from seating properly.
