I have that Fuzeblock in my bike also had one in previous bike. Well worth the money to set yourself up right. Keep tapping into different wires or the same wire many times will eventually lead to a problem.
Two leads to battery and one switched lead (hot) then you can run 6 accessories from it, some Fuze blocks have ability for 8 extras.
In my opinion it is worth the outlay.
I know nuffink, I see nuffink, It was not me, I was not here.
