Goodman B1378701 5-Pin Wiring Harness

The B1378701 is a genuine Goodman 5-pin wiring harness engineered as a direct-fit replacement for the APH1524M41AC package heat pump. This shorter harness handles a dedicated 5-conductor connection between the control board and a specific subassembly, using a keyed 5-position plug that prevents reversed or mis-seated connections.

Specifications

OEM Part Number: B1378701
Part Type: Control Wiring Harness
Connector: 5-Pin, keyed plug
Compatible Model: APH1524M41AC
Equipment: Goodman/Amana Package Heat Pump
Fit: Exact OEM replacement

OEM vs. Generic

The OEM harness provides the exact wire gauge, color code, and connector keying the APH15 board expects. Substituting a spliced or generic lead set invites intermittent faults and connector fitment problems. The genuine plug-in part restores a clean, factory-correct connection in seconds.

Installation Difficulty

Moderate. Kill power at the breaker, note the routing, unplug the failed harness, and press the new 5-pin connector home until it locks. Verify the latch is engaged and leads are clear of moving parts before energizing. Suited to a confident DIYer or technician.

Fitment checked prior to shipping. For confirmation, email info@nationalhvacparts.com with your model and serial number.
