@AllenMassey, I’n putting together some images and getting the pin out for you as soon as I get back to my computer.
Edit: Actually, most of the information was right here in the forum… check out this page:
On this image, note the yellow and black wires coming out of the front PWM:
On mine it looks like this:
Since the diagram is a little old, the other black wires aren’t running to this same pin, they are going to the same ground as the 24v fan and the ground from the gShield itself. This leaves only the PWM ground wire to be crimped like so:
Then as the diagram shows, connect the yellow and black wires to pins D11 and GND respectivly. This image from the instructions under Electronics Step 13 gives a hint as to where they would go and is were I took my cue from when putting together the machine in the first place:
Hope that helps.
