Wiring looms - replacement

Or a friend's 90 which was owned by an auto electrician.... every single cable was plain black :( 

Aircraft wiring looms, which are insanely complex and large, are all in white, but each wire is numbered with tags like John’s suggestion.

I guess in the case of an aircraft, everything is well documented and there are so many wires, colouring wouldn't help much. Out of interest, what do the tags look like on aircraft wiring?

For a Land Rover I think sticking to the original wiring scheme is best to help you (or subsequent owner) trace a fault in the future. Or if you do go down the route of using plain coloured wires with tags, at least a few colours with the tags may be helpful such as black for earths, red for lighting, yellow for instruments etc.

I agree - standard colour wiring is easiest.

The tags on ac are just white bands with black or grey numbers.  The sub looms all connect with locking multi-pin plugs, so it’s the fabrication that is difficult, not the installation.

We built a lot of industrial control panels during my early career. They were PLCs not hard wired relays, just in case you think I am really old. All the standard I/O wiring was in black with numbered identity ferrules, defined on the drawing and usually referencing the I/O address. It was quite a chore to apply them at both ends prior to crimping but once on and lined-up it made for a tidy job. The Klippon DIn rail mounted terminals to the external multi-cores, were also numbered but usually something simpler. That required a two-column cross-reference table. Spreadsheets didn't exist in the 1980s!

Probably some of that at JET still running until very recently Tim!

I would hope so Ross. That project was amazing and my bit, the cryo system, introduced me to incredible low temperatures. Liquid Helium was controlled at 4-5 Kelvin and when things went a bit wrong, returning cold Helium gas caused oxygen to liquify and drip off pipes onto the floor like water.

The plant is still running at the moment! Doing some STEP bits I think.
