Description
Weil McLain 591-391-786 Wiring Harness is an electrical interconnection assembly that is a routing and connection of control signals between the elements of heating HVAC systems equipment. It operates by co-arrangement of multiple conductors into a ready-to-use harness with connectors that are inserted into specific controls and sensors to ensure that the electrical routes are right and there are no splices. It is either fitted during the manufacturing process or it is fitted during service to replace or upgrade the factory wiring to make sure that there is a proper connection between the control board, switches, and actuators.
