I have a 2015 WRX-STI and itT is a ball. I am having some issues with the horn, I suspect it is the roll connector. I was going to look thorugh the postings. When you change out the roll connector you also need to "If the steering wheel and steering angle sensor are removed, perform “VDC sensor midpoint setting mode” of the VDC." The tool to do this is "SUBARU SELECT MONITOR III KIT." They are kind of spendy. I want to see if there is a less expensive alternative to this.
