Evening all, so before I wrap all these up anything else you think I should need? (Sorry should point out, I’m making a new loom for a 90)

I have wire rated 16.5 amps for all lights, wiper motor, pump, rear heated window.

I chucked an extra one in for the door and I have added 2* 25amp, 2*16.5 amp and a couple of 60amp red and black just in case... anything else maybe?

16.5A for RHW. Are you sure that’s enough? I’m sure mine is standard at 2.5mm, around 30A. Other than that, it looks alright.

Oh really, no I’m not sure to be honest.... I’ll have to look into that

Do found this

But I’m not sure what defender that’s for? Would I be right in saying if I stick a 30amp cable in there and it turns out to only be 10amp, it won’t matter as long as I only use a 10amp fuse.
I know the other way can cause a fire, using a bigger rated fuse than needed, but my logic (not that it’s the best) is telling me bigger cable is ok, when used with the correctly rated fuse...... but I have no clue if that’s right or not

I don’t know what year/model that’s from, but yes you can safely use a 10A fuse on 30A cable.

Nice one thank you, in that case I'll stick a larger cable through as well and then at least I have them both for when the time comes to wire it up.

Extra power supplies to the rear are always useful. If you have twin or 13-pin trailer electrics you need two power supplies. Plus adding things like rear power sockets or work lamps is much easier if the wiring's already installed. Route them into the battery box and make use of them as and when you need to.

If you have a spare pair of wires you can have central locking on all three doors. I fitted a kit to my old 90 and it made life a lot easier.
