IIRC Steve, the dealers & some independent Porsche suppliers (e.g.: the old
store Performance Products when in Van Nuys CA, etc.) sold those inserts to replace the factory function identifier inserts.
I always found it odd that those using these had to remember which switch did what, but apparently could not remember that their 914 was a Porsche without that line-up of reminders!
Cheers!
