Rb20de neo r34 -> rb25det neo

[Chidley]

Right, so I've done a search and can't find anything definitive but a few things that might come in hand, I currently own an r34 rb20de neo automatic (transmission isn't important really) which I'm in the process of converting to an rb25det neo. Now, the issue I'm having is I bought the engine blind and I think it might have been removed from a stagea or similar (in japan) because its missing the wiper wiring on the rb25det engine harness, and a few plugs are different, which is causing a little confusion.

My question is: does anybody have further information on the rb20de chassis plugs  (which connect to the engine harness and provide power & signals) (pics attached) so I can rewire it to work as correctly as possible? I've found a link on this marvellous website which Im confident can help me identify the rb25det wiring (credit to mitchee on here), just handy to have an input of the current chassis wiring before I spend countless hours trying to identify them the long way haha

For those interested, the link I found to the rb25det wiring is as follows:

 

 

Thanks again! (Ignore the dirty hands haha)
