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

[pekingduck]

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.

I also know of an instance where a rack intended for a 2013 Standard model would not fit the 2014 Standard. The original Honda Genuine Accessory (p/n 08L70-MGC-D30) was a low-profile rack, with the load surface about an inch below the level of the seat. The high profile ones are almost in line with the seat..

The 2014 rack was a high profile. Both 2014 Deluxe and Standard would use the same rack (p/n 08L70-MGC-N40), but the Honda kit also included a pair of extra extension brackets in the kit to lower the rear mount about 20mm. (these brackets are not sold separately.)

Buying aftermarket is a crap shoot, especially as many come from China and sending them back is nearly impossible. I think you would have better luck with the high-profile design.
