Next, remove the yellow/red wires from fuse 6, thin nosed pliers are useful here. There are three wires, 2 have uninsulated crimps and the third has an insulated connector. The uninsulated ones are connected to the RH end of the fuse (load) and the insulated one is the live feed to the LHS. (See post #1).
Loop these wires back so the ends appear at the opening in the top right of the plastic trim:-

The fuseholders I used are the stacking type and have one connection in and one out, this means the wires to the load have to be joined together in one crimp connector as shown in the photo. The wire to the supply side just plugs onto the fuse using the existing crimp.
I used a 7.5 amp fuse here.
