I have a Duo-Therm Thermastat I diconnected the wires without marking them. I have a yellow, blue, red, white, orange, and black wires. Termination points are +.75, cool, fur, hi fan,fan,gnd. Where can I find a wire diagram.

rv repair place should be able to order one

Y=yellow (a/c)
G=green (fan)
O=orange (reversing valve)
C=blue (common)
R=red (hot)
W=white, jumper to E (emergency heat)

Red = ground
black = ground
Grey/blue = Left rear (+)
yellow/black = ignition 12v
white/purple = right rear (-)
green/black = (could this be green / violet?) than it is 12v constant
blue/red = illumination
orange/green = left front (+)
white/green = right front (-)
blue/white = left front (-)
brown/yellow = left rear (tan / yellow) (-)
green/orange = right front (+)
orange/red = right rear (+)
blue = not used

Battery light green to yellow
Accessory yellow/black red
ground black black
Illumination light blue.red orange/white
Power antenna amp=blue blue
LF + orange/light green white
LF - light blue/white white/black
RF + dark green/orange gray
RF - white/light green gray/black
LR + gray/light blue green
LR - tan/yellow green.black
RR + orange/red violet
RR - brown/pink violet/black

Hello! Since I do not know if your vehicle is equipped with the Standard or Premium System I'll give both sets of wiring...You can identify which system you have by looking at the color of the ground wire...

Red=Standard and Black/Green =Premium


Standard...Constant +12=Green/Yellow...
Switched=Yellow/Black...Ground=Red...
Illumination=Blue/Red...

Standard Speaker
FR + White
FR - Green/Orange
FL + Orange/Green
FL - Light Blue/White
RR + Orange/Red
RR - Black/White
RL + Pink/Green
RL - Pink/Blue

Premium...Only power difference is Ground=Black/Green

Premium Speaker

FR+ White/Red
FR- Brown
FL+ Green
FL- White/Orange
RR+ Purple/White
RR- Blue
RL+ Blue/Black
RL- Yellow

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

red wire to the r section of the thermostat white (heat) to the w marked on thermostat Green (fan) to the g marked on thermostat yellow (a/c compressor) to the y marked on thermostat. Blue to the c marked on thermostat. Orange to the orange marked on thermostat.

here is a wiring color break down.

please rate my help.

a. Remove the cover of the thermostat.
b. Connect the RED wire from the air conditioner
to the “RC” terminal on the thermostat.
c. Connect the “YELLOW” wire from the air conditioner
to the “Y” terminal on the thermostat.
d. Connect the “BLUE” wire from the air conditioner
to the “H” terminal on the thermostat.
e. Connect the “ORANGE” wire from the air conditioner
to the “G” terminal on the thermostat.
f. Push the thermostat wires into hole in wall and
fill excess hole with insulation.
g. Mount thermostat base to the wall with screws
provided.
h. Check all thermostat wires on base to ensure
they are completely clear of the bimetal coil of
the thermostat. Adjust if necessary.
i. Replace thermostat cover.
If nothing operates on the air conditioner, remove the
return air grille assembly and verify the red, orange, yellow
and blue wires are properly connected (red-to-red,
orange-to-orange, etc.).
Next, disconnect the red wires and check for 12 volt
DC between the red wire from roof section and the orange
or blue wire from roof section. If no voltage received,
refer to Section F2. If voltage is received, the
problem lies with the thermostat or thermostat wires.
Next, disconnect all 4 wires (red, orange, yellow and
blue) from the thermostat. With the thermostat set on
COOL mode, FAN mode set on AUTO and HIGH, and
temperature selector set lower than the room temperature. Check for continuity between terminal RC (red wire)
and terminal G (orange wire); and RC (red wire) and
terminal H (blue wire). If continuity is achieved on each,
proceed with the next step.
Set fan switch to LOW. Continuity should NOT be present
between terminal RC and Terminal H, but present between
the other terminals (Y & G) and terminal RC.
If all of the previous checks are good, the thermostat is
good, do not replace it. If any one of the previous checks
are not correct, replace the thermostat.

red and white are positive and neg 12v
green is low fan
grey is high fan
yellow is cooling
blue is neg 12v(marked B-)
