Solved:
I opened Mmos first. *Then launced steam *Then launced PCars.
In options I chose *custom wheel. *Then went to edit assignments. I chose steer left and turned the wheel all the way to the left until lock. *Then slightly turned the wheel right. *It finally registered!!!! *After that all the other inputs registered properly.
I*don't know if having Mmos open made a difference but I had not had it open before and was able to get the wheel to register in edit assignments page.
All good now!
