Thanks!

Stock electric steering boxes adjust the steering assist based on the load (torque) applied in regard to the speed, tires and etc. This adjustment are done through the car's main ECU. Some Asian cars manufacturer s'(Toyota, Nissan and some Hyundai that I know) electric steering boxes can go to a default mode and apply some steering assist if they don't receive any signal from ECU while American car versions (Saturn or chevy Equinox that I am using) do not have a default mode which means if they don't receive the signal from ECU, they don't provide any steering assist. To overcome this issue, there are few companies on Ebay who sell some standalone modules which can send the signal to activate the steering assist but, since there is no ECU involved the steering assist will be controlled by standalone knob. I chose to go with Saturn/Equinox version since I felt they came out of an SUV which hopefully makes them a little stronger for a truck use rather than the ones come out of a Toyota Prius. Besides, me using big tires and wheels, I wanted to be able to adjust the amount of the steering assist to my liking rather than just relying on a default mode.
