So, sorry for what is most likely a stupid question. I am new to motorcycles and new to this forum. I just finally upgraded from my Yamaha Majesty 400 maxi-scooter to a new-to-me 2007 Vulcan 900 custom. I am loving the transition and learning as much as I can of this new hobby/culture. I was doing my oil change and cleaning of the air filter, and shining the bad boy all up for the first time since getting it a few days ago and I noticed an interesting cable coming from under the seat. it doesn't seem to be connected to the battery directly. It looks like it's coming from a harness. I am unsure what it is. I asked my Harley friend and he said he thinks it might be a data cable for diagnostics. However, I can't find anything in the manual about it. I was wondering if anyone could tell me what kind of connection this is for, and what the cable may be for. Thank you so much.
