Hi my name is Hal.
If I may offer a way to eliminate the EVO sensor that has worked for me in solving the light steering feel that is cause by a faulty EVO steering sensor.
We cut the wire at the EVO sensor and install two 10,000 ohm resistors , one on the red to the green wire and one on the gray to the green wire.
This keep the voltage low and eliminates the input from the steering wheel so the evo system takes no action. The pump does not have to be modified.
It has been about 6 yrs since i have repaired one with this method, but it works.
Here is the diagram to make the adapter up.
