Still Doesn't Work?

If you have bought a paddleshift steering wheel and the paddles don't work, it could be the wiring.
Smart altered the wiring when they face-lifted the 451 in September 2010. If you fit a pre facelift wheel
to a post facelift car or vice-versa, it will not work until you swap the 2 wires over.

How Do I Know Which Wheel I have?

Time to break out the multimeter and get testing. The connections are the same betwewen the 2 except
for the paddles so put your multimeter on resistance checking and put the probes on pins 5 and 10 and look
at the readout on the multimeter. If you get about 8k
Ω then they are the correct pins. If you get no reading,
place the probes on pins 8 and 9 and you should see the 
8kΩ show up on the multimeter.

Remember what 2 pins your paddles where using. Probably best to write it down.
