Quest Turn In Location

[Obtortus]

I'm having fits with this. I need to get the turn in location from a quest, but I can't seem to even get the coordinates. I'm sure someone else has done this and I have looked at many other Addons without figuring it out.

I see this function (GetQuestConditionPin) in the source code but I can't figure out how to call the stupid thing even with the pin manager from LibMapPins-1.0.

Any help would be appreciated, I've wasted far too much time on this.
