Dont have the EB - But my fusebox is in the Filter box. The right-hand side is occupied by a PC5.
Imo it's best fitted where you can get at it in a hurry. ime fuses always go in the middle of a trip, at night, in the rain, miles from anywhere. Not that I've followed my own advice here.
I wonder if you could velcro/Dual-Loc it to the top of the battery - it's not as if the toolkit is much use.
@PJ where under the seat did you put it? On top of the battery? I thought about the filter box as some have done but I have my radiator bottle there. Theres still room but its probably best to keep water and electric apart.
no water res there. mine is stock air system.
I have it Velcro attached fwd of battery and just behind the intake.
I don't use/need/have the power options as it seems plenty enough for me now.
I do have the handgrips, aux lights, GPS, dual heater seat, three power taps (one for helmet comms charger, one for phone charger, one spare) and battery tender pigtail.
Works great.
