Amana-Goodman B1378700SP Wire Harness

The Amana-Goodman B1378700SP low-voltage wire harness is an OEM replacement electrical assembly designed for compatible Goodman and Amana HVAC equipment. Its 16-pin connector provides an organized connection point for low-voltage control circuits, allowing operating signals to pass between the control board and connected system components. This harness is commonly replaced when the original wiring has damaged insulation, loose terminals, corroded contacts, broken conductors, or a connector that no longer seats securely.

Using the correct Goodman OEM wire harness helps preserve the original pin arrangement and reduces the risk of incorrect field wiring during service. Before installation, disconnect all power sources and compare the connector configuration, wire routing, terminal positions, and equipment model with the existing harness. Do not substitute a harness based only on the number of pins. Proper model and part-number verification is necessary because connector arrangements and control functions can vary between Goodman and Amana equipment series.
