Hit something?

[Bulldog]

I didn't see anything (very dark out) and I did not feel a bump on the tires.
But something sounded like a rock bouncing under the car.
My ABS and Battery warning lights came on and I seem to have lost power steering.
Other than the hard steering I can't tell anything is wrong.
Until I get a look underneath, I can't tell if I hit something that damaged the wiring harness, or if something broke off?
The ABS light makes me think the Wheel sensor harness is damaged, but I have not owned my Boxster for very long.
(About 4 months)
I was hoping some one could say if a wiring harness damage could account for the hard steering? or do I have multiple problems.
