Bongo Fury

i'm trying [ or my sparky is ] to change the electric blinds/cig lighter/mirrors to permanent feed whilst also wiring in leisure battery/ zig/ split relay. i've found loads of instructions on how to wire but nothing explains the mysterious connectors on the fuse board [ internal one in front of drivers knee ]. we have not seen these before [ the ones accessed at rear of fuses where wires from loom go in. anyone any idea what these are and how to get them out? if not how do we get new wires into the never before seen connectors??

What you normally do is take out the fuses depending what you want connecting (usually 1,6,7,8) from the front and push the wires with a small spade end (or a spade end cut in half) into the bottom section of the fuse, the wires then goes to the leisure battery through in line fuses.
This gives you the permanent feed from the leisure battery but still protected by an in line fuses using the same fuse rating as the ones you take out.
Fuse 1 is internal lights.
Fuse 6 and 7 are the blinds.
Fuse 8 is the ciggy socket and the radio.

Like this;

the four wires go back to the extra fuse box that you fit and just move the fuses from old to new.
