My AC works fine, that is, it cools at about 55 Degrees, starts at the correct temperature (I replaced the analog Thermostat with a Honeywell non-programmable one). The problem is the compressor will not shut off when the fan does, fan is set on Auto.
I have replaced the Run Capacitor, and the (don't know what to call them) the capacitors to start and stop the fan and the compressor.

It worked for awhile, however lately the compressor will not stop. So, trying to find the 3107541.009 Control Unit I find it is obsolete. After some research the new part number Dometic gave me was 3313189.000, which is also obsolete.
So I have ordered a 3313191.000 which RV Parts Country says is the replacement.

It is, I understand a digital replacement of the original obsolete unit. It came with no installation instructions and is considerably smaller than the original. Before I totally screw this thing up I would like to know if anyone has any knowledge of this installation.
I can only assume the wires are color coded the same as the old one.
Any input will be greatly appreciated.
Thanks
