At a Saturn dealership was my first job off the farm in 03.
And the first time I had seen electric power steering on Ion and Vue. And now the company does not even exist. And even my friends 07 Hyundai has electric power steering.
We did figure out that if we pushed a car into the shop, with engine off but key on, above a certain speed the power steering would kick in. Very strange feeling trying to arm strong steer a non running car and suddenly the steering comes alive and you almost fall over.
But yes I am sure there are many other uses for the systems. I am not sure the amp draw but wires weren't very big, and the wires were not yellow so it was normal voltage
