pictures of this wiring for reference. Be sure that you can see  
where the thermostat wires meet with the wall wires as they  
are typically different colors. You can also write in Table 4  
later in the section to record what color wires meet.  
Wiring the Thermostat  
MolexPlugs  
If your installation was done with the proper mating  
Molexplugs similar to Figure 5, then you can simply plug in  
all the mating connectors and move on to the section Mounting  
the Thermostat. The provided 9-pin (3x3) wire harness will not  
be needed. Not all installations will use all plugs, just ensure  
that every original plug has an EasyTouch match.  
Figure 5 - Inspect OEM Wiring  
You may find the Molexplug coming from the wall has a 3-pin plug and EasyTouch comes with a 4-pin  
plug installed. Use the provided 4-to-3 pin adapter harness (Figure 1) in these systems, where the  
orange/white wire is not used. If you have a 4-wire plug coming from the wall already then you will not  
need the 4-to-3 pin adapter harness. If you find the 9-pin (3x3) is used but not a 4-or 3-pin then you will  
use the relevant Direct-Wired section directions to complete the wiring.  
If the plugs are not the standard Molexplugs that mate with EasyTouch then you will have to wire it direct  
as described in the Direct-Wired section. You could also make up your own plugs but is beyond what Micro-  
Air can assist with.  
Direct-Wired  
The original thermostat in these systems will have wires coming out of the back of it that are  
connected to the RV manufacturers wiring harness, using a crimp-splice or similar. The wire colors on the RV  
manufacturers harness can vary, but the wires at the back of the original thermostat are always the same  
color for their use.  
Follow the thermostat wires the short distance to where they are spliced to the RV manufacturer’s wire  
harness. Write in the RV wiring harness colors in Table 4 below before making connections. Take pictures if  
you have not already for reference as well. Some thermostats and harnesses may not have all wires shown  
in Table 4. The important part is that every original wire has an EasyTouch match.
