This may have been covered on here before but I did not have any luck with previous advice. Does anybody have the pinout for the 575M6 going on an Anytone 5555 Plus/N model radio? The consensus is that pin 4 stay open because of the 5V. What about Pins 1 through 3? I've just purchased this radio and would love to wire my 575 to it. Thanks in advance!
