So I will briefly answer your question buy saying that sending the additional signals (shift up and shift down) through the back of the wheel ... (clockspring) WITHOUT running additional wiring is the purpose of this kit. In the wheel (behind the airbag) this kit (using a small interface harness assembly) piggybacks the shift up and shift down signals onto the horn wire .... THEN the MODULE (which mounts in the passenger footwell next to the audio poweramp) decodes the signal and in turn drives the horn relay and shift up and shift down functions of the shifter (only driving shift up and shift down when car is in "drive").


here is a pic of the interface (that piggybacks the signals in the steering wheel) and the module that decodes the signals (off of the newly formed "horn-databus" .... The rest of the KIT (additional harness's, template, shifter tool, etc attempts to make the paddle integration as easy, reliable and oem-like as is reasonable.
