Horn push connections

[Whitechameleon]

I've recently fitted a new steering wheel to my SC and have today received delivery of a new Porsche logo'd Momo horn push.

I was wondering if anyone knows where the earth goes on it.

My old (Italvolanti) horn push had 2 connections on it (positive and earth), but the new Momo one just has a positive. It does show an earth hole but with no connector.

The only way i can see it would work is if it doesn't need an actual earth cable but the copper wire causes it's own earth upon the pad being inserted into the silver ring in the middle of wheel.

See below



Please help, auto electrics are not my strong point.

Thanks for any help.

It makes contact on the curved metal piece. Just one wire to hook up.

Thank you very much mate.

Last weekend when I put my steering wheel back on I connected it to the outer ring. So every time I would try and mount the wheel the horn would go off. The sad thing is it took me 2 minutes before I was like DUH.... lol

Just got it on now. Works a treat, thanks again guys.

So it works now?
I just bought the same unit and it doesn't.
The only thing I can figure out is that the hub is not making contact with the car on the brass piece.
This is the piece that is spring loaded against the hub.
Did they send me the wrong hub or is there only 1 Momo hub?
Thanks

Should only be one hub. What happens if you ground the wire to the metal?
