B25 wiring loom supplies

[AltcarBob]

After an 18 months snooze in my shed I want to wake up my Starfire but the electrons have all leaked out of the nest of many times repaired dodgy crumbling wires, insulating tape and multiple different types of connectors. 

What are my options for keeping the electrons inside the wires. Should I get a new loom but the bike is fitted with Boyer sparks and has had the zenner diode removed plus I fancy fitting indicators. Seems daft to buy a new loom and straight away start chopping and modding it

Is there a kit that contains all the right Lucas wires and connectors plus instructions to build my own loom. I have never built a loom but have done a fair bit of wiring and some of my crimping has worked.

I've never heard of a complete kit like that, but Vehicle Wiring Products do all the cabling and connectors you'd need. My preference is to use the much better Japanese-style crimp connectors rather than the old Lucas bullets, but originality is never a big issue for me.

As well as VWP, I have a local supplier who does the thinwall cable which is much more useable than the type originally used. 1 mm² is heavy enough for most bikes. I also run earth wires to things like headlight and tail light as it's asking a lot for electrons to pass through paint, rust etc.

Is building a new loom a big job. I was hoping it was just a matter of removing the old loom pinning it to a board marking out lengths and then replicating every wire.

I have found a black and white wiring diagram anyone know of a colour version.

I prefer to build the loom on the bike, then you're not replicating any previous errors on someone's part and it's guaranteed to fit properly.

How much wire should I buy I think there's seven colours I will try and get the original colours. Also what wrap is best.

[V500]

I have four or five colours on reels so I can't say how much you'd need.
I prefer PVC sleeving to wrap, but as said, originality isn't a concern for me. The sleeving is dirt cheap on Ebay, and makes adding or changing a cable very easy.

The wiring on this bike scares me I have so far counted 13 colours of wire. There's unused wires dangling in the breeze and no fuses that I can find.

How do I start I am contemplating ripping all wiring out and starting again from scratch my original idea of copying the loom doesn't seem feasible.

[V500]

Draw out the wiring diagram in schematic form, then draw it as it would be on the bike, ie, headlamp etc to one side of the page, stoplight tail light on the other.
Then add wires to the bike using your diagram, (leaving plenty of spare at the ends) until it's all complete, and not forgetting plenty of earths!
Paper masking tape indicating connections and destinations works well for me. Simply tear if off when you're happy with it.

when I have made looms , I use 7 core or 13 core trailer cable - a 2 or 3 metre length is sufficient.
i can pull wires out of it at the appropriate places
works fine but of course not original

I am off to the supermarket to buy a ten pack of kids colouring pens and a large cardboard box to draw out the wiring.

I have done that before when fitting accessories to Japanese bikes. Think I have some tucked away.

I've either made the loom on the bike , or put nails in a piece of plywood .prefer the former method.
Always give yourself plenty of earth's, from battery to frame , to headlight , to rear lamp units, can't have too many earths

That looks like it would be very useful but for some reason I can't get to view the original and can only see part of the diagram. Possibly because I am trying to view on a phone. I have got as far as undoing the headlight connections before having to go and do something else electronicals scare me I can't even find a filling port to top up the blue smoke.
