eletric breaker

you may be able to trace the wires into the panel, 120 a/c or 12 volt dc? Unplug the unit so you don't zap yourself or fry something. Trace the wires into the box and see where / what they say o the fuse or breaker. That will give you a good start. You can also call the manufacture and get some info from them, old or new they should be able to help. Good Luck & be Safe! ! !

kit s/o---kitchen slide out?
s/o 11 ---11th position in box for another slide out?
yellow strip just a hold down strip for wires?
Really need more info. Fill out signature portion to give us an idea of what 5th wheel you own.

Ive always known S/O to stand for Strike Outs...so to me, it would be 11 Strike outs. Either the pitcher had a great day, or the batter had a miserable day.

Now, the yellow strip....its embarrassing but typically when I see a yellow strip, it means I didn't quite finish and leaked a bit. Usually, it doesn't require a change until morning though. Now, if its a brown strip, that's a whole different ballgame.

If this isn't helpful, I have no idea what you are seeing.

Need more information. Make, Model, and year of your 5th-wheel. Some one may have one and can answer your question right away.
