Looks like I need to do this - anyone done this and has some advice?

Stems from not starting when HOT in Le Mans - some very hot relays and also a burnt engine fan fuse.

Car now home and starts fine.

Means I can loose all of the none required wires in the so called bespoke harness and the excess loom length.

I can highly recommend the factory preference for scotch-locks and chocolate blocks. Also, do it all in black so it looks cool.

Hard luck Mick, hope it doesnt take too long. If it is anything like mine you will find loads of wires that aren't on the wiring diagram, wires running in illogical directions and circuit layouts which suggest it was an artist rather an electrician who wired them. Virtually every time I have to do a wiring repair it seems I can see a better way of doing it! Lots of good stuff around now. If you haven't already got one, do get yourself a copy of Car Builder Solutions catalogue and spend happy hours thinking how to use all the nice stuff available now.
Bear in mind that the price of copper is so high at the moment that the old wire is valuable, might make enough to pay for a single front indicator lens!!

You may laugh but the first car I wired was a Mini and I only had 3 different colour wires. Worked fine.

Luckily I never had to get into the electrics of my S2, but the wiring on the V8S is just plain silly in places. For example, the driving lights are operated by a relay and a switch, but the switch doesn't operate the relay. That would be far too simple. Instead the relay is operated by the dipped beam circuit and feeds power to the switch. Because - why wouldn't you want that?

I expect you'll find the S2 wiring was 'designed' by the same people so I hope you'll take the opportunity to fix it.

A full re-wire sounds a bit extreme, if the relays and fuse box are a bit ropey then maybe renewing and perhaps re-siting those is all you need (que comment from mr Phillips)
Also are you sure the starter is not faulty.

Different colour wires work exactly the same, they just make it a total pain in the arse to find faults with tongue out

Anybody worked on a Citroen DS or similar. All wires are green, with little numbered tags at the end. Have a look under that dash!!!
TVR is a piece of cake. but not terribly well cooked or with the best ingredients.

Remember those nice days when every British car used basically the same wiring colour codes? Oh for the days when green and white means righthehe

The old British wire colour system is very well documented so would make a good choice.

That is useful Alan, I wonder if TVR stuck to it enough for me to identify what some of the many spare wires were supposed to be for!

M series cars used all black wire with coloured tags - as mentioned above.

Rather fewer wires than on an S though...

Highly recommend these guys - http://www.vehicle-wiring-products.eu/

One tip - the modern thin wall cable is much better than the old school stuff - http://www.vehicle-wiring-products.eu/section.php/...
