I have a 2012 Prius C Three. I recently bought and installed a new headunit (just one off of amazon called the Hikity Android 13 Car Stereo). I was able to get everything working except steering wheel controls. I was able to identify the Key 1 and Key 2 wires and properly connect them, but when trying to connect the Key GND (SWG) wire from my new head unit to my car, the SWG wire is missing from my car's 28 pin connector, in pin 23. What do I need to do to get it working? Thanks!
So is the swg wire in another pin on that 28 connector? I don't have the wiring diagram for that car . But seems logical
