If you’re not using the standard airbox you could hide the terminal box inside it through that hole and then cover it with one of these

I think the best way to wire it (so you don’t have to try to attach stuff while the terminal box is obstructed by being in the airbox hole) using this position for the terminal box is to have extra long wires then connect them all to the terminal and then feed the wires through the airbox hole and send them off in the right directions (to stator, taillight, headlight) and lastly put the terminal through the hole. This method however does require you to take the wires off the stator OR just thought of this now, you could use connectors or just splice the wires together and shove them up into that hole that leads to the same place as the airbox hole where your terminal now is.
