OEM Goodman B1378701 5-Pin Wiring Harness

The Goodman B1378701 is a genuine OEM 5-pin wiring harness designed for the APH1542M41AA package heat pump. This keyed, pre-terminated harness links a specific component circuit to the control board through a 5-position connector, delivering clean, secure signal and power connections without splicing.

Install a new harness when the existing connector is heat-damaged, its terminals are loose or backed out, or you are chasing an intermittent connection fault. Replacing rather than repairing the plug restores reliable, factory-grade contact.

Specifications

OEM Part Number: B1378701
Connector: 5-pin keyed harness
Application: Component-to-control-board interconnect
Fits Model: APH1542M41AA (Goodman/Amana package heat pump)
Type: Pre-terminated exact-fit OEM replacement

OEM vs. Generic

OEM B1378701 comes with the correct keyed housing, terminal type, and lead length pre-crimped so it drops straight in. Generic pigtails force you to crimp each pin and match polarity by hand, increasing the chance of a mis-wire. The OEM part is the safer, faster fix.

Installation Difficulty

Easy to Moderate — With power disconnected, unplug the old harness, note the routing, and snap the replacement into place. No tools beyond a screwdriver for any clips. Typically 15–30 minutes.
