I just opened up the new used part. The 4 pin connector as mentioned is responsible for the steering wheel moving. This particular used part is missing the 4 pins on the circuit board. Seeing as I got this used part for $129. Should I just try getting 4 pins, inserting in board and away we go? Opinion?

It is common to depopulate a board if a feature is not required, but, engineers are usually careful to depopulate all the components they can because saving $0.50 on an assembly that they need a couple hundred thousand of adds up to real money. I suspect that they depopulated more than just the four pins you noticed.

Yup, didn't work. I did think of that being a possibility. All well, now I know for sure.
