Wire Harness Assembly 39321

The Wire Harness Assembly (part# 39321) is a genuine Tacony OEM wiring harness that carries power and switch signals between the cord, the on/off switch, and the motor on several commercial uprights. It is the pre-terminated bundle of wires and connectors that ties the machine’s electrical system together as one serviceable part.

The harness is made of insulated multi-strand wire with molded plug-in connectors sized to the machine. It fails when a connector loosens or burns, a wire frays at a flex point, or heat discolors the insulation — producing intermittent power, a machine that won’t start, or flickering under movement. Replacing the whole harness is cleaner and safer than splicing individual wires.

Replace the Wire Harness Assembly if the vacuum has intermittent or no power, you find a burnt or melted connector, or the insulation is frayed or discolored. Installation involves opening the housing and matching the connectors, so it is best handled by someone comfortable with wiring — our service team can do it if you prefer.
