I am renovating my engine bay wiring - everything is now working but I would like to put some extra fuses in as I have the original 2 fuse set up.

Vehicle Wiring do fused relays which look a simple way of protecting the lights/horn/fan wiring. They are fitted with a simple blade fuse. http://www.vehicle-wiring-products.eu/V ... relays.php

Any advantages or disadvantages anyone could comment on. Alternative is to fit a 4 or 6 fuse fusebox in place of the original, as detailed in previous postings.

The fused relays are a good, flexible solution. I made up a small aux. panel with relays for the low and high beams and the horn and located it out of sight (and out of the weather) under the dash.

Currently, I'm revising the wiring to incorporate a five-relay, eight-fuse panel that I built. There are relays for the headlights, horn, heater fan, and fuel pump; and fuses for each of those circuits, plus headlight drive motors (replacing the vacuum) and the lights other than headlights. I retained the two-fuse box (replaced with new) to handle the remaining loads. The new panel fits just behind the dash, all the way over on the left side.

Thanks Andrew

The original relays on my car are tucked up under the nearside fibreglass bonnet rest and it will be an easy swap to some new fused relays.

Andrew,

Do you have any photos of your installation?

Ah. The S2 was not originally blessed with relays.

What I meant was pictures of your new auxiliary panel installation. Sorry for the confusion.

Sure do... I've made a few small revisions since these were taken but the basic idea is the same.

Thanks, Andrew.

It looks great - nice clean work. That's going to be my next project.

When I installed an alternator on my S2, I used a fuse box from a Datsun 240Z. Ten fuse locations. I used the original bobbins in the body where the voltage control box was mounted. to mount the new fuse box. An adaper plate, cut to the size of the new fuse box was required as the holes did not quite line up.

The new box was a bit on the corroded side, but some vinegar cleaned up all of the fuse clips and made the box useable. I did some wiring modifications to the rear of the fuse box, soldering all the connections, to split the fuses between switched and non-switched.

I then rerouted the wiring in the wiring harness to the new fuse box. Now all the circuits are individuallt fused, both switched and non-switched. Then removed the original two fuse box. Only had to extend a couple of wires other than the new wiring from the alternator to the starter solenoid and then back to the new fuse location. I increased the wiring gauge of those wires for the additional amperage supplied by the new alternator. I then used some adhesive backed lable paper, stuck to the inside of the fuse box cover to create a diagram of each fuse, size and circuit. The cover is indexed so identification of each fuse is easy.

I just put power to the system for the first time. Everything works, nothing smokes - life is good

I did both, a fuse block for all the regular stuff and fused relays for the lights and horn with direct leads from the battery, which is really not proper as you want to have fuses as near the power source as possible. They are there to keep the wiring for becoming flaming heating elements with the only intent to burn you car to the ground. Here is my ATO fuse block. The fuse block and fuses are Marine grade so no rusting.

I had Autosparks in the UK fabricate a replacement wiring loom for my Elan +2. I sent the original as a pattern. I requested many upgrades including additional relays, fuses and larger gauge wires in important areas. I also had it wired for an alternator and voltage gauge.

I am posting a photo of my underhood showing the additional relays mounted on the firewall in lieu of the voltage regulator, added fuses and "standard" relays.

Old thread revival.
Are there any additions to this tread. I'm trying to split out circuits on an S4 and want better fuse protection. Would like it to look period if possible.
Any ideas
