Parts interchangability on US model years '13/'14 vs. '17?

[Lord Popgun]

I think the frame angle is a tad different on the '14 model so a '13 rack tilts up some. The heated grips are the same for all or almost all the bikes Honda has (maybe not gold wings). It's the connection kit harness that is model specific.

A USB power source is easy to add and there are a number of ways to do so.

The driving lights have been added by a number of members and I'll let them discuss those.
