VV Diesel Glow Plug Harness Quick Disconnect Connector?

Glow plug harness (AKA the Bridge) on the 01 Golf TDI comes with a male quick disconnect connector. Does anybody know the VW part Number for the Female portion of that quick disconnect connector/plug. My local VW dealer parts dept. could not find it in the IPC and the car didn't come with that Factory modification. Want to do the mod to make field maintenance easier.
