simple enough to make using a db15 connector. You should check the manual for your particular serial number radio to be sure nothing has changed but for mine the pinouts are as follows:
+12v - pins 4, 5
Ground - pin 2
PTT switch - pin 12
PTT ground - pin 3
Audio Ground - pin 9
Audio signal - pin 15
Mic in - pin 11
Mic ground - pin 10

All ground lines (2, 3, 9, 10) are tied together internal to the radio. All +12v lines (4, 5) are also tied together internal to the radio.
