I haven't seen much on this after extensive searching of the forums:

Is anyone here successfully using a JoyCon Steering Wheel Interface with the Evo X?

If not, what type of switching mechanism do these use (single wire resistive)?

I am looking to integrate the stock steering wheel audio controls with a windows machine, whether it be with a Fusion Brain (raw circuit) or a JoyCon (Steering wheel -> USB HID device, awesome option)

Any information would be awesome

 

I just started a thread looking for info as well.. I dont think its exactly what youre asking for tho. Im just trying to figure out which pins on the stock harness are used for the steering wheel controls.

 

9 and 19, I believe, pinside. These aren't included on the metra wiring harness. Grab an ohmmeter and test it out.. I am also curious
