Coupling harness for hvac mini-split system

Method of providing alarm signals to a HVAC mini-split system having a thermistor, a condensate overflow sensor and a HVAC electronic control device, the method comprising:

• removably engaging a unitary, releasable, self-contained, alarm coupling harness with the HVAC mini-split system, the alarm coupling harness including first, second and third electrically-coupled interfaces, by electrically connecting the first interface with the thermistor, electrically connecting the second interface with the condensate overflow sensor and electrically connecting the third interface with the HVAC electronic control device;
• at least one among the first and second interfaces directing a signal to the third interface when an alarm condition exists in the thermistor and/or condensate overflow sensor, respectively;
• and
• in response to a signal received from either the first or second interfaces, the third interface notifying the HVAC electronic control device that an alarm condition exists.
