I recently installed the EB headlight kit on my R3T but decided I needed a few other parts to finish the job to my satisfaction. I found this US website that has a great selection of parts that would be useful to anyone needing to locate hard to find connectors, terminals, relays, fuses, fuse boxes, tubing, tools and just about anything electrical for your bike. The nice thing is, he also carries the relays used in the EB kits if your looking for a spare relay. The guy is great to work with and he is located in NJ so you get fast shipping here in the US at a reasonable price as well. The Eastern Beaver website is great as well, but shipping is more costly and it take awhile to get the parts. Check it out and I hope you will find this website to be of some use to you if you need parts along this line.
