12v Power Access in 192RBS

In my two previous trailers, the lights were turned on at the light fixture. No wall switch. My new one has wall switches. If your light is turned on at the light and not on a switch, you will have both + and - 12v. If that's not the case, is there a smoke or other detector there in the ceiling that uses trailer power? Maybe you could tap into that. Worst case, use decorative conduit to get 12v to the fan.

Thanks. Our rig does have a main interior light switch at the entry door - although each individual LED does have its own toggle switch. However, the circuit would not be closed and power available at an LED until that switch was thrown, as I understand it. Great idea for the smoke detector, because there is one located closer to our vent than an LED light fixture. But it is battery powered, unfortunately. I'm busted on that one!

Saturday I called our dealer's service dept to speak to a tech who has knowledge of the wiring harness in the 192RBS, but only a skeleton crew was on duty. Hopefully I can get a good answer from someone tomorrow. And yep, just might have to settle for some decorative conduit to grab power, but finding a source is still the issue.

Appreciate your feedback.
