If the wiring looms have been damaged enough to need replacement, it may be
that most of that amount is labour. The loom(s) are almost the first part
installed when the motor is built. Ford won't repair a loom, they'll just
replace it completely even if only one wire of several is damaged.
I'd have an auto electrician look at it. I'll bet it can be repaired easily
and much cheaper. Where are you located?

Call a dealer and ask them, I would suggest.

FYI, there is a dedicated NG for the Focus at alt.autos.ford.focus.

ILLITERATE c.nt. Too stupid to be able to spell "anyone"?

That'll be the Vtech on-board 'my first ECU' then. Naughty thing, trying to
be hotwired!

It depends on what part of the loom(s) are damaged. Most cars have several
which plug together. If it is the main one which runs throughout most of
the car it could be a deal of work to replace. If a sub assembly which,
say, only does the engine it could be relatively simple. You need to
identify which it is by the wire colours and then look at a parts
catalogue for the car. A loom from a breaker's yard shouldn't be that
expensive, although make sure it is for an identical model.
However, any loom can be repaired. It would however require a skilled
person to do the job correctly. Most mechanics and so called auto
electricians bodge such things. The standard red blue and yellow
electrical crimp terminals most use are really not up to the job and
proper car connectors should be used instead. This is a source of such
connectors and the correct wire if needed.

As others have said, it'll depend on what's been damaged.
If it's just the wiring, a decent auto spark should be able to sort it, but
if connectors are damaged, then it's a totally different thing. Ford don't
generally supply connectors or repair kits, but some repair kits are
available from other sources.

If it does need a new loom, then you're talking about a complete front end
strip down, which will most likely involve the complete dash to be stripped
and removed, aswell as various bits under the bonnet, and no doubt a few
other trim panels. The loom itself will only be a few hundred pound, but
it's the labour involved that makes it so expensive.
I would advise against trying to swap a complete loom from a breakers, as
even seemingly identical cars can have different looms fitted (it only needs
a slight spec change, for a connector or two to be different). However, if
you need certain connectors, a breakers is as good a source as any, and just
cut what you need of the loom.

For repairing the wires, the best repair is done using heat shrink butt
connectors. They're quite expensive, but are what most manufacturers supply
for patching in repair kits for wiring looms. Just strip the wires back,
crimp them on, then heat them up, and they'll shrink on and the glue will
bubble out the ends, making a fully sealed repair.

It comes down to whether it's an insurance claim or not. If it's a claim
then the insurance company must pay to put the car back to it's condition
before the damage which would require replacing the loom. £2500 sounds about
right. Otherwise a competent autoelectrician would be able to do a perfectly
adequate job for much less. The only problem I can see is if the connectors
are completely thrashed. Even if this is the case you could cut off a
section of loom from a scrapped car and reconnect to yours.
