New Frig 12 volt wiring

Normally I copy and look at wiring diagram to figure things out. However, this is creating a little bit of concern. MY unit is a 1979 29' Ambassador with rear bath Frig and electric incoming is on street side with frig at the side of last pantry door. There is 110 volt plug in that works. the other two switches I have no idea except I believe they are 12 volt. the other factor is the flasher with two wires were laying beside the switches on the floor and not connected to anything. Original frig was only connected to110v. Maybe it was a 110 only frig.
Two options: 1. Run a circuit to 12v panel and forget the original setup.
2. Do it right and ??? current setup. (I extended the wire that goes with the gas line but connected as original.)

Any suggestions?

New fridge

The original Dometic in our 1999 Safari 27 died during a recent 2 week trip.
After researching options, we decided on an ac/doc unit. The hardest part was getting to dead one out. I'm not an electrician nor handyman. At any rate, I did what you are doing now and asked for help in the forums. In our '99, there were 2 wires that went to the old fridge 12V control panel. And there is a 2 outlet standard receptacle wall mounted. I did get a professional opinion/look see from a marine mechanic. Most of the time the Isotherm will run on the 110. However, he said the wire gauge for the 12V was more than enough to handle the less than 5 amp draw of the fridge when it runs on 12V. We had a carpenter do the interior finish mount. Everything works great. Looks great. And the whole install cost me my time and $140. for the carpenter. Some day maybe I'll redo the wire, but it now is way down the list. Sorry this got long. Hope it helps. Good luck.
