hi. I have a fiat stilo abarth and just pot a second hand steering wheel on it. now when I try to change gear with the paddles. it wont change gear.? can you help p.s I just found that the horn is not working. thanks

I'd guess that you've not fitted the wiring in the center of the wheel correctly. The paddle connectors go in the 2 empty blue sockets in the picture below.

The white connector with red and black wires is for the horn.

How much of the second hand wheel did you fit?
Did you change any of the parts form your steering wheel to the replacement one?
