Actually I think the #7 fuse is a 5 amp too and if it is and you use a 5 amp for the ibus adapter side then it doesn't matter which one goes where since both would be 5 amp. Just make sure what amp the fuse is that's in slot #7 of the fuse box. If it isn't a 5 amp and you use a 5 amp for the ibus adapter make sure to put the 5 amp in the shunts wire side and the fuse that was in the #7 slot in that slot on the shunt.

Again it makes sense once you have the shunt.
