458 steering wheel leds

Is there some one that know's where i can find the scematics of the steering wheel electronics.
As special the electronics of the led's how the led's are communicatiefwhit the rest of the car?
I whant to make a oder led unit like the BMW M4.

 

As far as I know, on the M4 there is a module installed in the dash to go along with the electronic wheel, so I presume the LEDs communicate with that module over radio

 

Do you maybe know how i can obtain the schematics of this unit?

 

No idea sorry - I doubt BMW have made them public.

 

I only want to know how the connection is made in the Ferrari 485?
The rest i can make it myself!
I also change the colors of the led's for a few costumors of me, and led lights in the enginebay!
