While building a wiring loom from scratch is possible it is very time consuming (as you've seen by the quotes).
The main problem is not the wiring as such but where it connects into things, the connectors.
Most of the connectors are custom made for Ford so you can't get replacements to match up with things like the instrument cluster, the column switches etc etc.

I would say you do also need to have a fairly good understanding of car electrics to be able make a loom from scratch.

But, i doubt if it's really that bad, yes, sure, it's probably been messed about with a bit, especially where people have added the Quantum specific modifications but these can be replaced with new sections, it's a lot less work than starting from scratch.

If you can get hold of another Mk2 Fiesta loom in better condition then it will make things a lot easier.
As long as you can solder ok and have a big enough soldering iron then you can just cut sections out and join in new sections of loom.
Cover the joints with heatshrink (put on before you join the wires !!!) to keep any water away.
The wiring loom in my 2+2 has sections from at least 5 car looms in it, 2 off Mk2 Fiesta, Mk4 Escort RS turbo, Mk3 Fiesta EFI and Sierra (for the rear lights).
It's lasted 15 years so far.

Hi all,

Hope you are all good!

My quantum has served me very well.. up until now. The issue is the starter motor has seized up so that should be easy enough to fix. The main issue that i am facing is the wiring. Not long ago i had some minor work carried out by a local garage who informed me that the whole wiring of the car is in a very bad state. (I am saving you the several adjectives he used to describe it!) I think that the car is basically going to require a complete basic re-wire. Having very little knowledge off car electronics, I began too look at companies that do this but quotes of near £1000 have shocked me.

The question i have is that if i spend enough time attempting to re-wire my car could I do it relatively easily. I do have time to spare but balancing my job for Aston martin and my OU degree means I only have several hours (or less) to spare a weel so I would have to do it over a long period of time.

I think that if i can not do this myself i will have to sell the car, which I love so i would rather not have to do that. Ideally if i could find someone that would like to have a go on the wiring as a project with me paying for parts etc would be ideal but I understand that this is a perfect situation that I am unlikely to find. ANY TAKERS??? ;)

Any comments or suggestions you have would be greatly appreciated, or if anyone has any interest in a quantum to buy as a project let me know
Quantum coupe, red, number 99

Many thanks
Shaun McSorley

Hi Shaun
I am in total agreement with Jim. Most looms that I look at in Coupe's are usually better than they look.
If you can get the car to me so I can take a look, I may be able to advise / help etc

Thank you both very much for your quick response, might try and learn more about car electrics online etc before I think about having a go with it?
Where abouts are you eddie?

Many thanks

I agree with Eddie and Jim
 
I would work in sections / functions and splice in new sections. If the ford connectors are broken then try and source replacements from a friendly car breaker - the last one I dealt with cut off the main electrical components and sent the rest of the loom for scrap a long with the rusting shell. A chat and few £s and he supplied the switches and connectors I wanted with "tails" which would be spliced back in my loom.
 
The Haynes Manuals give the standard wiring diagrams which are usually straight forward to use.
 
But Try this website for a tutorial (you may need to copy / paste the addresses in to your web brower)
 
The following website gives an overview of the BSI standard for colour coding wiring
 
Sources for materials might include (no recommendations implied) and I am sure there are plenty other advertising in the magazines
 
The Car Builder Solutions Catalogue / Website is a good read....
They even include a couple of VERY basic wiring videos (LOL)
 
Additionally
The Kit Car magazines have run articles on custom built looms vs. modular looms vs. build your own in the past. Might be worthwhile looking for these. Try

I am just north of Bristol, in Chipping Sodbury.
Thinking about it, if you wish, I can have a word with one of my contacts, may be able to get a second hand wiring loom complete. That would make life easier for you. I have got looms from him before. I can get a price without obligation.

Unfortunately Ford don't use this standard for the wiring on Mk2 Fiestas.
Does anybody know the standard they did use ?

The Ford (non?) standard. Most diagrams I've seen have differed from the wiring and are also in German - doesn't make the task simple!

When i "rewired" my 2+2 i did nothing more complex than cut out the really bad bits (mainly the earths, did from scratch) and then traced each wire in situ end to end checking the entire length, didn't see the need to remove the whole loom since if the individual wires are sound and the insulation intact they ate as good as new, it was the end connections that caused problems but most got replaced, a haynes manual is invaluable along with all the good friendly advice on here, i couldn't have done mine without it

For some reason whoever put my 2+2 together hadn't a clue about electrics. Although he used an existing loom he chopped and changed it, felt that twisting wires together with sellotape insulation was a good way to do things and that the thickness of the wire was irrelevant to the current going through it... 

One thing: those blue butt connectors? If you don't have the *professional* tool that makes a proper hexagonal job, forget it - particularly with different thicknesses of wire. The only clean way to extend cables is to twist inline, solder - with a big enough iron! - and heat-shrink over the joint.

Hi Nigel

I currently live in Leamington spa however this weekend I am moving to a place in Bishops Itchington, but the house is practically in Southam i think. I would love to meet up anytime you are free however this weekend I am moving in there and will then be looking to bring my car down here from Manchester where I am originally from.
Would be great if we could organise something tho!

Many Thanks
Shaun McSorley

Where are you located?  You say you work at Aston Martin which is Gaydon and I live nearby in Southam.  Although what I know about the Saloons and 2+2 can be written on a postage stamp (I built an Xtreme), I am very knowledgable on vehicle wiring etc.  If you are nearby and want to meet or drive it over sometime would be happy to take a look and help advise you on best direction to go.  I'm with Jim, in that I would be surprised if it was so bad that it needs a complete rewire, at the end of the day the car is running (once starter replaced) and so would have thought you could start at one end and gradually work your way through the car, without a major down time.
