yep just did that install on saturday and posted a pic as well

 

i know it can be tough to get them sobs to fit under the seat of a dyna also,but the thing you must do is to take the original wirng harness with all the connectors and pull them all up out of thier nesting place,this will give you the room you need to place the pig tail connection down into the nest first then all the other smaller cables and connectors can be put back in around the larger pig tail plug,so when you are all done the pc pig tail plug should be completely hidden and the pc module should be sitting where you are know showing where you have pig tail connetion to the ecm.
