2013 model. Seems like I have seen some literature in the past showing a 7 pin connector. I could use a convenient 12 v source for a foam marker I am planning on coming up with.
The DK and NX have cut out mount for the 7 pin plug on the rear right. Above the 3ph lever.
But I found out it was a dealer option. From my snooping around there are a lot of wires that look like this could be a plug and play install with a set of drawings.
