3313 Adapter Harness for Dometic 3313189.000 A/C Relay Control Box.

Sale price $ 38.57 Regular price $ 46.28

Harness adapts Dometic's 3313189.000 A/C relay box to other brands and models of RV air conditioners. Used when converting from an analog to a digital thermostat.

If your existing air conditioner does NOT have a 6-pin molex plug (like many Duo-Therm Dometic A/C's do), this adapter may be your salvation. But first you must identify that you are able to access the following 5 wires: 120V white common, 120V black line, green or yellow ground, high black fan speed and a low red fan speed wire coming from your air conditioner. If you have identified those five wires coming from your air conditioner, then you can probably convert from an analog thermostat to a digital by ordering this adapter and Dometic's 3313189.000 relay kit.
