Solved Fan Extender doesnt respond to M106

So I went to a dual extruder, got the fan extender to control the parts cooling fans using pin 6. The fans successfully responds to the sample test code:

void setup()
{
pinMode(6, OUTPUT);
}
void loop()
{
digitalWrite(6, LOW);
delay(5000);
digitalWrite(6, HIGH);
delay(5000);
}

But, it doesn't not respond to the M106 command in part files g-code. Intel on the web seemed to indicate the redirection would be automatic in Marlin when #define MOTHERBOARD = 34. Apparently it does not.
Anyone have correct intel on this?

 

You redefined the pin # under motherboard 34 to be 6 from 4?
