Wiring loom tips

Doing up an old series Landy, wiring is shot. Stripped the loom out of the disco that provided the motor and axels.
I’m stripping out all the unneeded wires, any tips of what to do/not do?

My tip would be not to p about with the wrong loom and go and buy a new one, plenty available from about £80 for the main bit and £20-£30 for other sections that you might need. If you’re going to the length of doing it up you might as well do it properly, after all it’s probably a very good investment and very much worth the effort.

Avoid the fleece loom tape/wrap..

There's one made by Tesa that's used as OE by many. Does a proper job and looks factory.

Tesa loom tape all the way. A a good wiring diagram with the pin outs and take your time.

if you want to do a proper bomb proof job use raychem

It’s going to be a long winter in the middle of nowhere Iceland. Project to learn as much as anything. It’s not standard now anyway.

Nearly finished wiring my series 3, granted it’s a new repro auto sparks loom and follows the original vs your disco loom - but found this useful, might be of some use to you?

Lucas Wiring Information

Would advise running headlights through a couple of relays as well, so you’ve a good choice of upgraded headlights, but disco maybe already has that sorted? Also would try and reuse the old switchgear you’ve got, newer repros aren’t always the greatest quality

Best way I found to do it was run the wires to where you need them, getting them through the bulkhead plate panel things to behind the dash will be the trickiest part, then connect either end and find the best run for the in between.

Wanted to use the switches that are on it and to use modern lights and the fuse box (though I may go and buy a more compact one) on it.
I was wanting tips on how to strip out unnecessary wires without making a birds nest and getting lost. Cutting wires away from fuse box etc.

Throw the disco loom away and start from scratch, it will be quicker and easier .

Have you tried shopping for car electrical items in North East Iceland when you can’t speak the language?

Have a look on YouTube for Project Binky. One of the episodes covers the wiring loom work - probably around number 25, if I had to guess.

Do you need to cut wires out? I would personally try and leave well alone as modern looms can be confusing as things don’t always go where you think!

Watch out for diodes wired into the loom. I think they're used to stop relays/solenoids energising each other. Someone will know more about it than me.

I need wires for the lights and engine stuff, fuse holder and basics. I started stripping out the central locking/ window/ door wires, got rid of the egr control wires need to figure out what ones are the airbag wires. Just want to get rid of as much as I can.
the abs is coming out too.

I’m sh!t with electrical work, but I’ve the time now to learn a bit now!

Airbag deploy wiring is all in yellow, youll need to refer to a diagram for the powers n grounds etc

Another vote for buying in the loom from elsewhere, as there will be so much redundant wiring and changes of ancillary locations that the Disco loom would need to be almost completely reconstructed, which will mean inevitable mistakes, and you’ll go demented trying to trace faults.
Spend the winter doing an Arctic Trucks conversion instead, like the Tonkas that drive around Reykjavik

In my head, the easiest way is to plug in everything essential, all the sensors the engine needs and your fuel sender and radio etc. What’s left should be the non essentials, strip them and harvest the cables for wiring up the lights and heater.

I’d also spray WD40 into every plug before plugging up. Save any water getting in.

You might have to wire a brake switch in unless the original loom is still there. Don’t forget to make sure you have good earths and grease up the connectors.

If you have to connect old to new, especially where the connection might see moisture, grease the cables before putting them in a connector block.

I’m sure you already know, but keep any insulating tape you want to use in a pocket next to your skin. Nothing more infuriating than cold tape snapping!

I’ve been enjoying your Icelandic adventures, was there for a day for work. Seems nice there!

As I said buying one is a no go.
i was looking at pictures of a brake switch to double check that it was as I thought, was on eBay, double the price of what you would pay at home to get it up here.

The Ford was rescued a few weeks ago. About 6 tons

fitting the 300 tdi and axles to the series is enough for just now when all you have is hand tools and a power supply that the current rises and falls so much so that welding is a thing you have to time to hit a sweet spot.
