Need A/C conversion wiring help.

I have a Carrier A/C unit I want to install for my second unit in the bedroom.

The Monty is wired for the Dometic units, and has a RJ11 control wire for the second unit. Dometic is very secretive about what the four wires on the RJ11 cable go to.

Can anyone tell me what the four wires go to so I can connect them to the proper terminals on the Carrier unit?

I have decided to install the Carrier in the bedroom with a separate T-stat.
We are leaving in 10 days on tour (6 weeks) and there is not enough time to get replacement parts if I burn out some controller in the process.

Use the non-ducted type, with a built-in thermostat. That way, you only need to hook up the power lines and leave the control lines disconnected.

I have done just as bad Moon proposed. I put a Carrier low profile on my 3150 a few years back. I bought the inside diverter that had the controls right on it and didn't have to mess with compatibility of the wall thermostat. The ceiling ducts were blocked from the factory since I didn't order it with 2 A/C's, so I left the blocks alone and just used the diverter assy as it came. Too bad Carrier no longer makes RV A/C's. My low profile near blows ice cubes in the bedroom if you turn it down low enough.
