I am in the process of doing a frame off restoration on a 5 window b1b. It had previously been partially restored, but never completed, especially the interior. The wiper switch was left dangling under the dash. when I went to move it to its proper location, I noticed another switch that has never been correctly placed, but I'm not sure where it would go. It appears to be a fan control switch for the heater. There are no "holes" in the dash where it might go. The four "holes that have been filled are: Head lamps, panel lights, ignition key, choke and throttle.
I've included a picture off the Internet to indicate what I'm describing.
Any ideas?
