Secondary fusebox- where?

FlyingPete · May 27, 2016

I've converted my 90 from glass fuses to the modern blade type. In doing so, I used 3 8-way fuse holders in the standard central fusebox, giving room for expansion. All good.

But, pondering wiring up my new lights, I've considered there really isn't the room in that location for much extra wiring and relays, so I'm considering relocating some of them elsewhere. If I left two of the fuseholders, that would leave 16 slots- enough for the standard circuits (12) rear wiper and heated window (2) and radio (2).

I though about putting a box with fuses and relays under the bonnet somewhere- that would power the 12S tow socket and the extra lights on the front, all of which have relays controlling them. It would have its own dedicated supply from the alternator terminal. I'd then only need a couple of extra wires coming through from behind the dashboard, keeping the wiring coming into the cabin to a minimum.

Trouble is, there's not a great deal of space to mount a fusebox under there and all the convenient mounting points seem to be used. I could put one in the battery compartment instead, but then the control wiring to the relays gets more convoluted.

So those of you with extra circuits- where do you keep the fuses?

I've put all my extra stuff under the driver's seat(110 rear tank) tool store thing. I then drilled a suitable hole to take conduit fittings and used steel reinforced flexy stuff to run wires along the chassis to the engine bay.

I'm trying to decide the same. I'm rebuilding and putting in an extra feed from the battery box to either engine bay or dash somewhere. I'm going to run the can cable in the existing ducting and then either through bulkhead or just into engine bay.

Its for luxuries such as radio, to start with it'll be off main battery, but I also Want to fit a second battery and split charge.

I was going to run cable now and decide for sure once dash is in (perhaps by the end of this weekend!)

having slightly less wiring than space shuttle with my conversion- battery box and behind passenger seat

I've got loads two extra fuse boxes in my battery box, works well and being close to the battery makes the fuses more reliable . I'm not sure what most of them are for yet but I'm getting there.

I've had them under the seat, in the cubby-box, under the bonnet etc etc but in recent years have settled on this layout with them on the dash.

A single suitably rated (switched) feed to the fuse-box and then there are short links to the co-located relays and switches in the console. Permanent feeds (alarm, interior light, clock etc) are fed from a separate fuse-box which is still located in the battery-box.
Looks a bit "in your face" but it is practical and means nice short cable runs, also if a new circuit needs to be wired in then it is easy to get to.

Mines behind the passenger seat on the bulkhead. Close to the battery, out the way but easy access.

Snazy bulkhead! Also a nice fusebox and relay pack. Where did you get them from? Is it a modular design? (different bits fit together).

Fuse & relay boxes are modular type, can't remember the make but are available from lots of suppliers. Yes, they just clip together and the relays plug in so easy to work with.

Take a look at Vehicle Wiring Products as they sell them.
Relay box is:- Product Code:RB4U.
Fuse box is:- Product Code:FBB16U.
