FC JDM Wiring Diagrams

Hello Everyone! I'ts definitely been some time since i've posted on here. I am in DIRE need of help. I need to find the JDM Wiring Diagrams for the FC's. Im not after ECU pinouts, i need full wiring diagrams as the ECU pinouts are the same between both JDM and USDM. Seems only USDMs are posted on this group, or i cannot find anything JDM.
I need to verify the pinouts for the X-11 and X-10 plugs on the engine harness for the Series 5 specifically (for now) but eventually will need to verify this on S4 as well.
So, if anybody has anything they can share that would be awesome.
On a side note, if anybody is interested, i do cater for FC and FD with fully terminated wiring harnesses for pretty much the majority of factory ECU's. So feel free to email (email, dont use the forum's messaging as i DO NOT check that).
Thanks in advanced!

The one bellow here is the X11 20 way, shown from both sides. I will add the X-10 one as soon as i have a proper pic of it.

Hello!
I have the JDM wiring diagram for S5.
I have tried to attach it here (not sure if it worked) (also not sure if that's allowed)
I found it online somewhere last year. Ill try to dig out the link to the site.

Hey thanks!
I did have something similar to that one but i gotta admit who ever copied it didnt do a very good job of making it look good, and the page splits on the big diagrams are kind of kinky or out of order. I can get google lens to kinda translate a few things, but since the document isnt searchable it makes it a wee bit harder.
Im still waiting on some people down under to see if they have anything available they could send me, but so far nothing. Not even a decent japanese version. Ive got what seems to be the compliment to that Wiring Diagram, but its too big to upload. I'll try to get it on GoogleDrive and post a link.

Well boys and girls, it's taken some effort but here it is. This is confirmed with the JDM S5 Turbo Pinout and there a couple of minor differences between a JDM pinout and the USDM, can anybody confirm that a JDM S5 does not actually have a check engine light like the USDM?
Colors are in fact what the JDM wiring indicates on the Manual. Currently working with a customer to verify that its 100% accurate, but it usually is. Im still trying to determine the full harness wiring diagram, as i still need the body plug verified. I have pics of them so i know exactly what the colors are, so i might be able to verify it, but if a wire doesnt go back to the ECU its a little harder. Will keep working on this.

Ok, update on this. I have managed to confirm all but 1 of the wires going to that 20 Way connector, which is called X-23 by the way!

So for all our Turbo JDM FC owners that would be interested in a fully terminated (Stand Alone) ECU harness that will maintain AC operation, coolant gauge on the factory cluster, tach, etc.
