Bird on a wire - the rewire begins

Horn push should be on the left hand (indicator) stalk ?

It ain't on mine

Then you've got the wrong switch!

Looking back at your photo, correct switch has a square hazard button and those purple wires just visible should be for the horn.

Agreed but also looks like my column and wheel boss do not have the capability to connectthe horn.

On mine the original wheels both had the push button style center to operate the horn but it was unused - horn operates from the button on the end of the stalk.

Hi Penny

is it ok to have the relay activation coil feed fuses fed from the 'switched live' via the Ign relay and have the 'power' feeds to the relays fed from 'permanent live' fuses or should both the power and activation feeds be via the 'switched live' fuses?

I will be purchasing busbar feeds for both perm and switched fuse banks.

Looks like I'll be needing approx. 26 fuses, the bus bars come in either 10 or 20 spade outlets. So will need three - 2 perm/1 switched or 1 perm/2 switched

with a few spare. Also need fuses not fed from the battery (Main/Dip/Flash/Rear Fog)

or am I reading too much into this?

No you're not reading too much into it, it's all good thinking

Battery supply to relay terminal 30 is the best method

Switched supply to relay coil terminal 86 can be whatever you choose

Fuse the relay outputs not the inputs. You won't need to fuse the relay supply If your battery is very close to the fusebox

If the battery is below the fusebox and relays you will have to have it in a box so that it doesn't gas upwards and end up corroding everything, perhaps you're using a sealed battery or one with a venting tube that vents out of the car through the floor, or maybe a gell type????

I can easily post you a fusing/relay wiring method

[Penelope Stopit]

You won't be able to fuse the circuits correctly if you use bus-bar fuseboxes, this is why I earlier posted you a link to the correct type of fusebox

[v8s4me]

If the busbar in the fuse box is the common earth, like this one what is the issue?

The issue is that one side of all the fuses are connected to a common positive, they are not individual fuses

[v8s4me]

But surely each circuit is individually fused and protected by its own separate fuse?

Yes you are correct. The above fuses aren't individual hence they restrict the method of fusing to fusing the inputs, magpies needs to be fusing the outputs

The proposed busbars are completely separatand before the fusebox. They are basically to distribute the large battery cable down to multiple spade connectors then these wired to the individual circuit fuses.

magpies, have you got a link or image of the fusebox?

[magpies]

Fuse boxes are these

And the busbar

Yes a fuse / relay wiring method will be good. I've emailed you.

I like that a lot

But think you will also need a relay for the boot solenoid if you have one?

Thanks

Looks good Stoppedit

minor comments / probable changes to keep the totals down to that I've alreadypurchased

I'd supply the dash illumination from a side light fuse - almost all LED
probably not worth fitting relay to side/illumination as very little current draw and switch is designed for no relay
Rad Fans - agaon I'd keep with original Sierra Cossy design of only one fuse and relay
Car does not have electric windows
probably require a boot solenoid relay
Fogs supplied by side/head switch so not on with sidelights
don't know yet if injectors needs a fuse/relay but will check with Jag wiring diagram

If I do require more fuses / relays I will obtain

Once again cheers Penelope

Glad to be of help

Tomorrow I will ditch....

Side Light Relay & Illumination Fuses

Rad Fan Circuit 2

Windows Fuse

• *And Add***....

To Diagram Rear Fog Lights Switch connects to Side/Head Switch powered when headlights are on and switches supply to fuse

To Diagram****Boot Release Relay**** Needs to be fitted in the boot somewhere as this method uses least wiring, the relay only needs the fused supply from front to back

I don't know what setup you have at present for switching the boot release relay, if you are only operating it from the back you could run a cable from front to back and have a dash button

Let me know what you want me to show for the boot release

The thing Is I've started so I'll finish.....all being well when the jobs completed you will have a correct diagram of the finished wiring for the relays and fuses

I hope you now see the benefits of fusing the outputs from the relays rather than the inputs to the relays

Cheers, time for a beer
