I've done a lot of searching and have come up blank with a part number for what I need.
I purchased a 4-spoke MFSW from vw_nc_dude (thanks!) last week in order to replace my plastic (no buttons) 4-spoke.
The part I am looking for is the wire/ribbon cable (not sure it would be called a harness) to connect from the buttons to the controller. The button assembly on the left side has a connector for this cable that I presume goes to the controller. Below are pictures stolen from threads to show what wheel I'm talking about. Any help is greatly appreciated.
