I suspect you have uncovered general 120 volt receptacle wiring so far.
There is a two part device called a tracer or tick tracer, you can get them with clips or a plug end. The toner can trace wires but if wires are running together you have to be careful.. for false signals from induction. Some work on low voltage and others on regular 120v the latter usually being much more expensive.

I will chime in with my question here....I am in the middle of replacing my unit as well. The wire that feeds my A/C looks like standard Romex, only its black, and not shielded in that stuff that the rest of the trailer wires are. When i removed my unit, there was the one wire for the A/C and another wire that just appeared to be "looped" through where the opening is. Any idea what this wire is ? I am glad I found it, as someone, possibly the PO had peeled back a portion of the wire insulation ( for testing maybe ) and then just wrapped the bare wire back in electrical tape. Which was now almost useless. On to my question....there is a switch with a small transformer over the galley that seems to turns the A/C unit power of and on. When checking with a volt-meter, when the switch is on, it reads a full 120v to the two a/c wires, with the switch off, 62 volts. Can anyone tell me what this little transformer is for ?

Here is a link to a couple of the pictures .....

From the look of the diameter of your taping job I have to question how you were able to separate the 3 wires, hot, neutral, and ground.

You should never bury a splice joint in electrical wiring. You should cut a hole in the ceiling close by and put in a shallow box, wire connectors, and plank cover with wire nuts on each of the 3 connections.

You did not say where you are reading 68 volts but it sounds like there is a problem. You should never be able to read other than line voltage or open in an AC circuit. Reading half voltage indicate a problem, possibility something wired in series and dropping half of the voltage across that item.

Thanks Howie...The joint was not a splice, the actual wires were never cut, just the insulation peeled back, I felt it was better to tape them back up really well, rather than cut the wires and install a junction box. As for the voltage, it was on the black romex that feeds the A/C. with the switch on, there was 120v across the two hots. with the switch off there was 62 volts across the two hots. Mind you the old A/C while it did not cool, did come up, power up and run the fans. I Will grab a few pics of the little transformer in question and put them up as well.

There is only 1 wire that is hot in a 110 volt circuit. You should read 110 volts between the positive lead, Black, and the neutral, White, or ground wire, Green.

Please help us figure out what is up by describing where you are measuring 68 volts by wire colors.

Update on the drain tube...The copper tube exiting the bottom of my A/S about 1 foot inside of the front street-side wheel is the drain for the A/C. It runs straight up along the door opening between the kitchen and sleeping area. It is enclosed within a piece of wood trim that doubles as the door edge trim where the expandable door attaches. Near the ceiling there is a 90 degree elbow soldered on and a stub pipe where the clear plastic hose was attached.
