What does software voltage pin on the obdii control?

 

if I assert a voltage on that pin will it change the mode of the DME?

On early 986/996s with DME5.2.2 (non-eGas), pin 60 on the DME (Software Voltage) is used when re-flashing the fuel map with a PST2.  At the start of the flashing routine, the PST2 applies 12vDC to that pin, and it disconnects it when the flash is complete.
