The question is a little vague to answer in any detail, however I'd suggest you work out if you need to rotate it using the animator or in playmaker itself.
If you choose the animator then have a read up on sending variables between playmaker and the animator.
If you choose to do it all in playmaker then you'll need to look into taking the data you have (control input, AI etc) and making the data drive your streering wheel rotation.
Best of luck!
