the red and black wires in the 6 wire harness.
C12 Vdc to the red wire; –12 Vdc to
the black wire.
c. Connect the previously run furnace thermo-
stat wires (if applicable) to the blue wires in
the 6 wire harness. The polarity of these con-
nections does not matter.
d. With slight pressure push the divider plate

will only fit in one direction.
h. Plug the freeze control into the matching
black 2 pin connector in the electronic con-
trol box.
i. Insert the freeze control sensor into the
evaporator coil fins approximately 1″ above
the bottom of the coil fins and on the left side.
