I am getting to the detail stages on the 78 Spider and it's time to give attention to some of the smaller details. It came with an Abarth steering wheel installed minus any horn button, just a single wire in the hole. I have looked at a few of the usual parts houses, but it isn't clear (to me anyway) what I should be looking for. Before I go any farther in the search I thought I would see if anyone has any experience or guidance. Thanks.

can you post a pic of your wheel?

I will do that tomorrow.

It's been awhile since I tried to post a photo. Let's give it a quick try....

If Mark doesn't have one, try
p/n 12021-23 from Spider Point

These usually have two terminals to choose from when attaching. Attaching the wrong one will cause the horn to run continuously Try before pushing button into the hub.

I bought one from Fiat Inc. on ebay. It took me a while to decide whether to get it. I'm glad I did. It is raised and looks so cool. In the pic it looks like it has a flat top. It's deceiving.

Ordered a red Abarth button from Spider Point today to go with the nice red interior....
