- Black/White - SWI Ground to SWI Feed (Pin 23)
Pink/Red - SWI Circuit 2 to SWI 2 (Pin 22, controls Phone On/Off, Mode)
Purple/Red - SWI Circuit 1 to SWI 1 (Pin 21, controls Up, Down, Vol +, Vol - )
However, there's a 3rd SWI Circuit on Pin 24 (controls Enter, Back, Right, Left).When I did the firmware update ( ADS-RR(SI)-TOY01-DS (1.1) ), there were functions for these buttons. Are you able to correctly interpret the button signals without using this 3rd circuit, or do I need to connect that wire somewhere? Kinda like to know before I start pulling the dash apart.
