2009 empty, usable fuse location?

[schleppy]

I am currently using an "add a fuse" to power my tachometer, using the fuse location for the cigarette lighter. For some reason, even with both fuses installed in the "add a fuse" the cigarette lighter won't work.

Does anyone know if any of the other open fuses locations in the interior fuse box are active and ignition switched? If not I may just tap off the stereo wiring.

Thanks!
