Coleman Mach 8232 series to Atwood
I have two ancient (2003) Coleman A/C units which are ready for replacement. The system is run by the Intellitec 00-00591-200 controller and a no-longer-available Climate Controller also by Intellitec...

Thanks, Chris.
I read a similar detailed swapout from a guy with a Mach 3. I could not see in his wiring the same kind of stuff that is with the Intellitec. My coach is a Fleetwood Flair 33R 2004 gasser. I should add that the A/Cs are ducted.
The Intellitec in my coach has a dual thermostat in one unit (on the wall outside the bathroom) and a controller behind the power box in the bedroom. The cables are separate 110 ac to each (I assume from the transfer switch controlled by the controller. It also has a bunch of wires running into a cable that has to be going to the A/C. In the Coleman Mach (8632B6764 which Coleman denies is a good number) each unit has what looks like a 9-pin connector (I found that the 9-pin connector goes to the outside to the caps, fan and compressor (DUH!)) and several two-pin connectors. One of the two pin connectors goes to a thermistor attached to the evaporator coil, the others that have wires go to a stub cable that attaches to the cable from the coach. It has 6-pins in the stub cable and only four are used on it (rear unit) but the front unit has all six wires and appears to be feeding back to the thermostat with all six wires. I think both of these cables go to the controller in the bedroom.
Any comment on that?
I am going to pull things apart a little more to see if I can identify where these wires go - especially the 9-pin connector (it is laced into a protective netting so the wires are hard to see.) I am fairly certain that I have 6 wires to the controller for the Intellitec.
What I want to do is save the shedding feature which means that I will have to get the thermostat of the Atwood to run things when the Intellitec says it is ok by providing it with power.
If worse comes to worse, I could just install without the Intellitec, but..
Anyway, right now I am trying to figure out where these 9 pin (or whatever they are) go to. If they go to the intellitec, I will install the one thermostat (rear) in the bedroom where the cables go and the other next to the front door - along with the furnace feature - the wires (6) all appear to be there. Otherwise I might have to surface mount the thermostat wire on the front unit. Running the rear thermostat in the bedroom will be easy unless I decide to put it where the furnace control is instead.
The rear unit is in the main cabin to the rear of the kitchen (which is behind the entry door). The front unit is just forward of the entry door. The 6-wire cable appears to run toward the rear side of the door. The 4 wire cable that attaches to the 6 wire stub appears to run back towards the bathroom dressing area where the function controls and thermostat sliders are located. It is reasonably accessible from above (I hope).
Any thoughts?
