In order to add a print fan and the servo for my ABL on my new itty bitty flex dual extruder, It was suggested I get this RRD-FAN-EXTENDER. I wish to use it to plug my ABL servo and a print fan. The motherboard is set to 34 as the instructions state. It also says this RRD-FAN-EXTENDER is "plug and play". I plugged it, but it doesn't play anything!

  1. Is there a wiring diagram that will show me where to plug the servo, and where to plug the fan?
  2. Do I need to alter any of the firmware so RAMPS knows that there is a fan and servo?
  3. Do I need to configure the firmware to tell RAMPS the I now have a RRD-FAN-EXTENDER installed?

I tried looking this stuff up with no luck. Any help to get this working would be appreciated.
