I have a 2017 WRX that I am installing the SW on and the diagram shows to wire Maestro into the 28 pin harness. My car has a 12 pin and an 8 pin harness to connect the new radio. The factory headunit had a 28 pin harness on it as well as the 12 and 8, but it is not used on my new Alpine ILX-W650. Is that the 28 pin harness I should be tapping into?
