Wiring loom
bruxby-clive:
Here we go next instalment.
The first thing we need to do is wrap the loom in self amalgamating tape, starting at the front we keep wrapping it over itself,

until we have the whole loom covered,

Then we need to to install the additional PVC sheathing to protect the loom as it goes round the head stock.

and then secure it with a little more self amalgamating tape.

The next thing to do is fit all of the connectors.

I started in the middle and fitted the 4 & 6 pin multi connectors and single bullet connectors, these are all just crimped on , I apologise in advance for the quality of some of the photographs.

…very nice.
I assume you wrap the branches < the main loom? How do you secure the ‘last turn’? Is the self amalgamation enough?
Was recently trying to find a wide SA tape to replicate the original (eg 30mm) - no success. I note you’re using a 15mm or so tape.
Not worked with thin wall before; do the smaller diameters give issues with crimping? If so tips as to best succeed; which tool are you using?
I’ve a 50yo car I want to reloom - would you suggest thin wall over conventional - my main concern is (as mentioned) the terminations let alone the ‘unfriendliness’ of a thin-wall under dash spaghetti. Weight, nor space are an issue…
Ta,

Hi Simon
To answer your questions;
1. I find wrapping the self amalgamating tape around itself before moving down the branch is enough, although I go around both sides of the branch before moving on.
2. With the 1mm thin wall I have doubled the stripped end over on itself before crimping to provide a bigger area for the crimp to bite on. I use this crimping tool https://www.vehiclewiringproducts.co.uk/c-51-crimp-tools/c-119-non-insulated-terminal-crimping-tools not the greatest but adequate if only doing the odd loom, if I was doing it regularly I would go for a ratchet crimper like this; https://www.vehiclewiringproducts.co.uk/c-51-crimp-tools/c-119-non-insulated-terminal-crimping-tools/p-269-ratchet-crimping-tool
3. Given that thin wall has a greater current carrying ability and makes the loom thinner in size, I would always use it, you can still get the old style cable, but I think the range of available colours may not be quite so good. It is probably down to your individual choice, although hopefully, Big Al may be able to provide a more technical view on the matter, he is far more knowledgeable than myself.
