They have a 5A inline fuse, and I don't think the wattage was actually all that high.
Definitely you need a relay that is switched by a wire that is only one when the key is turned on, unless you want to develop your bump starting techniques
. : I did it on several bikes so it must be simply. Just go to any auto parts store and get a generic horn or lights relay, should have a diagram on it that tells you which terminal connects to what, power in, switch, ground, etc. I usually just use a wire going to the tail light, and be sure there is a fuse into the system. Oops, I see you have a fuse. I usually use the cheapo glue on elements that cost about $30 but this install, on a Guzzi, I used Bikemaster, that I found for $45 and were simple to install with a 5 level controller.
