The Goodman B1378701 5-Pin Wiring Harness is a genuine OEM connector assembly for the Goodman AEPF426016BA air handler. This 5-circuit harness typically links the blower motor to the air handler's control and power connections, carrying line and signal leads through a single keyed plug. Corroded pins, heat-damaged insulation, or a cracked connector can cause an intermittent or non-running blower and hard-to-trace electrical faults. A fresh OEM harness restores a solid, properly keyed connection.

OEM vs. Generic

This genuine Goodman OEM harness ships with the correct connector keying, pin-out, and wire gauge, so it seats positively and matches the mating plug the first time. Generic substitutes or splice repairs invite reversed pins and loose crimps that can leave you chasing phantom faults. OEM is the clean fix.

Installation Difficulty

Easy. Plug-and-play: kill power at the breaker, unplug the old harness at both ends, run the new harness along the original route, and snap the connectors home. About 15–25 minutes. Note the original routing before you remove it so the new harness stays clear of moving and hot components.
