steering wheel help

[Audifan]

My S8 had a 3 spoke steering wheel installed some time before my ownership. I'm not sure which model it came from. I bought a decent used S8 steering wheel which has the tip buttons. Since my S8 was converted to a 6 speed manual trans, I'm not concerned with hooking up those tip buttons to operate.



So I went out to the car to swap out the steering wheels, first thing I noticed that there is a triple square nut that mounts the steering wheel. So I bought a triple square bit set online. Another thing I noticed is that there is this white circuit board looking panel behind the metal plate in the steering wheel. I have no idea what it's for. You can see it in this picture below.




Upon further inspection I noticed that there is 2 wires that connects to this white circuit board looking panel. It has 1 black wire and 1 brown wire as seen in this picture.




The S8 steering wheel that I bought doesn't have that white circuit board looking panel. Here is a pic of the S8 steering wheel.
