There are significant variations from one model year to another and in the body section of a 2+2. Up to seven variations on each segment: engine room, instrument, dash, console and body. And I'm not counting anything other than U.K. manual cars - autos will be a different set again....

"2+2 and 2 seaters" are odviously 260z or newer i can see how the looms may vary but did the loom for uk 240z's vary?
I have a scrapper 240 that i think i may take the loom out of, tidy up and test, then put back in mine, but i think it's a year or so newer.
ZHead, thanks for the offer but keeping my sam running has to be done on a shoe string as buying a 350 went down like a lead balloon with the missus, so subsequently i've got to provide a hot tub and conservatory this year.
I sort of thought a wiring loom (if available still) would be priced around £200.00

73 one will be different in places, as it had intermittent wipers and stuff and probably a load of other minor changes. It would be a lot easier to make that one fit than a 260z one which is completely different.
I tried to get a new engine loom made up by Autosparks ( www.autosparks.co.uk). They could not get the japanese connectors but said they could remake a new loom using new wires spliced into the original connectors. Worth a try perhaps if that 73 loom is an unknown quantity.

I have a 72 240 which is a one piece loom. Also have a loom out of a 71 which is two piece.

This is for manual, U.K. cars only. More for USA models, Australian models and a whole new set for autos.....each part number change is marked with "new part does not fit former, former part does not fit new". Do you want me to go on? The same situation is true for the other loom components. There are no "one-piece" looms in 240Zs to my knowledge - they all unplug at a common connector set under the dashboard. If you have a loom made, you will be having it made for your car. OEM style connectors are not available "off the shelf" and they are all different to make the looms "plug and play" with minimum error. Making a loom is very labour intensive, so most of the cost is not in the materials content. You would need a jig to get lengths and joins exactly right.
The best wiring diagrams (and lots of other good information) are in the Clymer 1970-1979 Shop Manual, but they are for the USA market. They show EIGHT separate wiring diagrams for 240Z/260Z/280Z plus 1979 280ZX spanning nearly thirty pages at the back of the manual. Anyone interested, I have one only brand new copy available - £19.95 inc. postage, no VAT. First PM secures it!
Now, if you wanted OEM 280ZX loom sections cheap, I have loads of those.....

It's not the cost of the wire and the connectors it's the cost of a skilled man's time building it - I agree it's a lot but to me it is worth it. I do not want electrical failures.
I know where there is a New Old STock engine loom for a 72 car..... not complete though, just the engine section

I'm building a new engine loom for my 240 and if you are doing an exact replacement, its not that hard. Mine incorporates lots of mods and is becoming a bit of a pain. Luckily a freind of mine owns a company that makes race car looms and he let me use his workshop and materials. His company is Harness engineering and his name is Ian. If you contact him he may be able to help, but its not cheap and he is very busy.
