EasyTouch RV 356
Micro-Air provides a 9-pin harness (Figure 2) that will be used to interface between EasyTouch and the RV
manufacturer’s wires. One side plugs into EasyTouch RV while the other wire-end side is used to make your
new wire connections. You will have to source or reuse electrical connectors to make these connections.
EasyTouch will also have a pre-wired 2-pin connector and a pre-wired 4-pin connector attached to the back.
Connect the provided 4-to-3 pin adapter harness (Figure 1) to EasyTouch. Strip away the black heat-shrink
on the orange/white stripe wire if the orange/white stripe wire is used. Cut off the 2-pin and 3-pin plugs as
needed and use electrical connectors (not provided) to complete the installation per Table 4. Any unused
wires or plugs you can cut short or leave untouched.
When you know where each wire goes you should begin cutting wires. Move through them one at a time,
replacing an OEM thermostat wire with the appropriate EasyTouch wire until all the wires are replaced.
Check for Additional Hardware – Software Setup for Later
You must check your wiring to determine what
additional hardware your system may have. Later, you will
use these findings to configure the software in EasyTouch RV.

gray wire next to orange and red.
Re-apply Power
Restore DC power. The thermostat screen should light up and boot into the main menus. This will
happen if the four power wires are connected properly. All other wires control the outputs or are sensors.
Restore AC power so that your appliances can run again. Move on to the section Mounting the Thermostat,
