Your local motorcycle dealer will have the caps (I got mine at a honda dealer) - an auto parts store will NOT have the caps.
I got my wire at NAPA auto parts - not sure there was much of a difference for me with the wire, but there certainly was with the caps.
Might help to put your city (or the nearest big city) in the location field of your profile or even in the signature. Seems like you've had a couple "where do I get it" questions and that'd help search gurus say hey "...such and such should have it"
