Just ordered and put on my new 9 bolt steering wheel from CJ pony parts in my 66.

But I'm confused how the horn is supposed to wire up. There are 2 wires coming off the hub, but only 1 open connector on the back of the horn button. There is another wire coming out of the back of the horn button but its connected to one of the 2 existing clips...any idea how the heck thats supped to work? See attached picture.

Naturally there were no instructions included.
