Dometic Thermostat

[igofshn]

I have a 3 wire thermostat and want to put a house thermostat. Problem wires are not standard. Red, white, light green, light blue, brown, purple and black. No yellow wire??? Anyone know how to wire it up?

Unfortunately you can't just replace the thermostat with a residential model. You also have to replace the control box in the A/C. You're fortunate in that it appears that you have enough wires in the thermostat cable. Even though they're not standard colors you can use them if you decide to continue with the changeout.
