Best place to look would be the Dealer. As previously mentioned get the Service Manual and the Parts Catalogue.

Extremely well written tomes!

 

Get the HD service manual. The part numbers are usually in the Owner's Manual
2017 Service Manual part number list-

The parts manual are available from Harley online- the SIP (Service Information Portal) has wiring diagrams, Parts Manual and Owners Manuals.

Use the search at the top right and search by year and model, ie 2014 Street Glide

 

I get mine at swap meets. The one I go to there's usually a guy that sells them for $20 each or two for $30.
