Alternator wiring refurbish

Having made an alternator sub-harness (see other post), I now need to refurbish the alternator stator/field coil wiring. How do you guys go about this? The wiring seems to be a white insulation wire (high temperature plastic) with a coloured glass braid over and an overall glass sleeve over that which was possibly white/natural when new. I am fairly sure that the braiding over each individual core may have been coloured to start with though. Luckily the wire strands themselves are tinned type (unlike the rest of the wiring which is bare copper) and look like they will re-crimp easily enough (or solder if you don't have the correct crimping tool).

I am tempted to just refurbish as far as the rubber grommet and leave the part which is inside the alternator housing well alone on the stator and field coils. Just wondering what you guys do? I reckon I could dye the sleeving the correct colour if I knew what it was originally. Getting the sleeving in white/natural is hard enough in small quantities, so getting three different colours would be a nightmare (my guess on braided outer colours (2mm ID bore) would be yellow on the stator and green and white on the field coil).

Interestingly, the clear covers on my 10/69 K0 alternator female connectors (Hitachi) are not the heat staked ones but the type, which are almost the same as the ones that Vintage Honda Connections sells (i.e. slip on type) . I noticed that on the pic of an early 750 sub harness that ChrisR kindly photographed for me that these slip on covers on the female part were fitted (See pic attached).

BTW on the hard to get rubber parts (like the grommets on the alternator wiring), which harden, I have a magic industrial concoction, which softens them up really well (not the essential oils stuff that the SOHC/4 site has trialled but one used in the rubber industry). I was sceptical about it but I treated a rock hard K0 inlet rubber with it about 18 months ago and it is still as supple as the day I treated it despite being in both hot and very cold ambient conditions.

You all probably think I am mad going to these extremes but I reckon if members use their expertise to dig deeply into components,  then this paves the way for everyone else to do a superb job without shelling out lots of money. I am not knocking Yamiya but their repros are not always up to the standard to be expected for the prices they charge.

Here is a dutch webshop that sells this. I know this guy, he sells a lot of electrical parts which are hard to find:

Thanks Marcel and Ash,

i'm searching for:

woven glass, impregnated with silicone sleeving.

Where to buy?

I'm searching for the white, used in the sub-harnes wire.

But also in other diameters.
