Don't sell it, just rewire the connector.  I don't have the SM20 but I do 
have an SM6 that I rewired and it works fine.  In the SM6's mic connector I 
connected the mic audio (white) to pin 1, the PTT (red) to pin2, and the 
gnd/shield to pin 7.  The K2's jumpers were set to the MD2/MH2 configuration 
with a resistor between pins 1 and 6.
