Refrigerator/electric help

[Carman]

I’m replacing a household refrigerator from previous owner with a dometic 1350. Behind the fridge I’ve found an unknown black and yellow set of wires capped off w/ wire nuts. Looks to be 12 gauge wire but in corrugated sleeve but not in the typical yellow or white rubber housed wire insulation. Not hot with ignition off. Does anyone have an idea what it is? Already have two plug wires there. This is a third that originates from front and under slide out. Can’t trace it further.

Probably solar panel pre-wire. In the past yellow has been the positive for the panel (yellow - sun, get it?) and black the negative. The refrigerator area is a typical location to bring it out. That's where mine is. You cold confirm this in your manual. If you don't have one, you can download it at Airstream.com.

Thanks. Appreciate the reply. Frankly, I was hoping someone would say it was a 12v dc wire for my replacement Dometic because I haven’t located it yet. Curious thing is the solar is operating fine. These wires are just terminated with yellow wire nuts in the refrigerator enclosure.
