I had it hardwired in my Subaru, I just vampire tapped the auto-dimming mirror using the hardwire kit. The Focus wires seem to be an inconsistent mess. I'd like to tap a power near the fusebox since it is most convenient. I just checked the overhead and that's a mess as well.
I don't want a toggle switch, I like things as automated as possible. No point in running a switch to an accessible locale when I could just unplug the detector just as easily.
I think your problem is the fuse that you tapped into it. Could have a thermal overload switch in the circuit which shuts off after a set time. I'm not an expert in that field. Use the fuse # I recommended (#85) under the glove box. I've had no problems after a year, and it would save you from finding and splicing wires together.
