Why doesn't my horn base plate have a tab for the ground? Options

[GeorgeKopf]

I'm assembling my horn pad and can't find a place to connect the brown ground wire from the contact ring. Do I have the wrong base plate?



I think this is what it is supposed to look like:

And the PET Parts List for a 1974 doesn't show the contact pin:

Thanks.

(could be wrong on this, but basing this off 911 stock setup)

The black wire from the fuse panel makes the horn sound when it's grounded. Unlike an aftermarket MOMO you don't use a second wire because the stock horn button is a pad that is spring loaded. When you depress the horn pad, it contacts the metal ring and grounds it. The horn wire connects to the pad, then the pad touches the metal of the column grounding it and sounding the horn.
