Yes from several sources. I used Road Island RI wire. They are great. I ordered the color I wanted and with the tracers in what ever quantity you want. They also sell woven sleeving. The wire is great because it is modern thermoplastic wire with a cloth over braid. They sell harnesses too. I made my own up because I ran ground to every light added fuses and turn signals. You can see some of this in my photos.
