No takers on this question? I'm surprised there isn't one ace mechanic out there who knows his late model Rocket inside and out.
The 2007 PDF manual I have found here just isn't cutting it when it come to answering this question. I can see from my most recent tank raising there have been some changes to my late model R3T. I have been in contact with a dealer and base on my VIN number, he can get me me a current manual for $106.87. It's back ordered for 2-3 weeks. I guess if I want a definitive answer I'll have to order a manual. Thereafter, I will be able to answer all of your question about the 2013 electrical system and wiring.
