I've recently obtained the official wiring diagrams for the JDM Gen 2 Rev A (sorry no Rev B/C).
I'm in the slow process of scanning, translating and uploading them to a thread over on uklegacy.com. As there could be a lot of stuff I'm not going to try to duplicate it all here. You can find the post here.
If you have any requests for pages drop me a message on uklegacy.
