20b_silvia

Over the last few months I've been gathering a few wiring diagrams and workshop manuals that I've found for the Cosmo. Some diagrams have both the 13B and 20B but I was more 20B specific.

I am wanting to re-wire my engine shortly so thought they might assist someone else thinking of doing the same. I don't care if you share them around, but maybe put a link back to these forums as every bit of information that we can gather will make the job a hell of a lot easier (anyone read Japanese?)

Please take note that all of these manuals are in JAPANESE. If someone has more details or anything else please feel free to PM me as I am more than happy to host.

Part A - Starter and Alternator
Part B - Engine Control System (ECU)
Part C - Dash warning lights
Part D - Windscreen wipers
Part E - Head lights and fog lights
Part F - Hazard lights
Part G - Air con control
Part H - Automatic transmission control system
Part I - Rear window defrost and other random ****
Part J - Communication system
Part K - Power windows
Part L - Power mirrors
Part O - ABS
Part P - Power seats
Part Q - Cruise control
Part T - ELR (NFI)
Part W - Wiring schematics
part X - More wiring schematics
Part Y - Ignition switch

Joint Box
TWS Box
Wiring Index

I managed to track down a person that uploaded a convert of ECU pin outs
ECU Part 1
ECU Part 2

JC Cosmo Manual

20b_silvia

Some chassis fuse box / relay identification.







- unable to find any information about what relays these might be for, perhaps someone could assist in that one.

Also looking at re-wiring the standard coils, ignitors to run the standard ECU with a painless or keep it clean wiring kit.

this is really good.

what would be sick also if there was a FD3s 99 series 8 body loom diagram made up that shows what body loom wires need to connect to a aftermarket ecu to get the dash working ect?

Then i will have eveything i need

Does anyone have sections A thru J of the JC Manual?? that copy seems to start at K??? or am I missing something?? I've seen this file in other places missing those sections too.


OOOPPS - think I just stumbled on the reason can anyone confirm that there was never a section A - J???? https://www.rx7club.com/showthread.p...=20b+cosmo+PDF

I was excited to see this post (albeit really late) as I'm after the 20b body harness and ECU wiring diagrams but unfortunately all the links are now broken.

If by any chance anyone still has access to them could you let me know? I would absolutely appreciate it! email: heath@sakebombgarage.com or PM if you've got em!

Thanks

I would also like to have the wiring diagrams and workshop manuals. I bought a 20B Eunos Cosmo, so anything I could get related to the body and engine would be very helpful. Thank you.

This information would be really helpful to have. Is there anyway that a copy could be emailed (fd4rotorz@yahoo.com) or reposted somewhere else? Any help in obtaining this invaluable information would be greatly appreciated. Thanks in advance!

All should be up now.

Let me know if any links are broken.

Links are still broken

I'm thinking this should either be updated or should be removed as a Sticky if it has broken links. It's kind of useless to have it, yes?
