Pigtail and Handle Harness Assembly D434-3714B

The Pigtail and Handle Harness Assembly (part# D434-3714B) is a genuine Tacony OEM replacement part that delivers electrical power through the handle of the CleanMax ZM-500 and ZM-700 corded commercial upright vacuums. It is item #24 in the handle and bag assembly, and it ties the power cord, the two-speed switch, and the motor circuit together into one serviceable wiring harness.

On a corded upright, this harness takes line power from the cord and routes it up the handle to the switch and down to the motor. Because it flexes every time the machine is used and stored, the wiring inside is a wear item — insulation can chafe, connectors can loosen, and a break anywhere along the run will cause intermittent or complete power loss. Replacing the complete assembly restores a clean, safe power path rather than splicing a single damaged wire.
