Horn connection

Cavalier 1992 mileage 133,302 km.

I left mi car parked on street, I assume someone tried to steal it because the center of the steering wheel was poped off.

My problem is that the wire that connects to the horn from the steering wheel got disconnected.

When I do insert the cable into the hole it belongs, I hear the horn, but I cannot make it work when I put the steering wheel center again ¿is there any particular form to put that wire again in its correct position?
