Bristol 403 Wiring Diagram

[Colin from Hull]

Hi
I was reading some old posts and a few years ago a member was modernising the 403 wiring diagram making coloured version did the pdf ever reach the forum.
If anyone has any advice putting new loom into the 403 please share your knowledge.

Cheers!

Here you go, Colin, as a .jpg.
I can convert it to .pdf if you need.
This is for a 401, so there will be some detail differences, and you'll want some add-ons for modern conveniences.

My advice is firstly to obtain a new wiring harness made especially for the 403. It will have all the correct terminals on each wire termination and each wire will be tagged with connection details. Such harnesses are available from Vintage Wiring Harness in Australia, and are excellent. VINTAGE WIRING HARNESS

The next big item is getting the correctly fitting rubber grommets for the body holes and getting the stiff loom through them and in the correct location along its length so that the various 'arms' of the loom fall naturally through the correct parts of the body. Once the centrl part of the loom is in place, the rest is a matter of haveing a selection of the correct loom clips to keep it in place. Good luck. A wiring diagram is not particularly helpful or necessary, if you first have the correct loom which is made exactly for the car.
