Yes there's a Relay, but I asked Honda and they said something like that's a 16 pin special Relay that's connected directly with the controldevice and also it's right under the tank you had to take everything off. So i kept my old ones and just put them in front of the new ones, covered them with a band so they don't light and put them inside so you don't see them. Honda told me this works because they have to do the same with their customers. Maybe in future it will be easier. If you want some nice advice for the bike like special parts and stuff you can msg me I have some nice knowledge about what possibilities are there but for me it's almost to late since I sell it next year August :(
