So, after some long delay, here's the rest of the project
AS I left last update – it was in the middle of updating the engine harness, originally from a 1990 IS for adopting the 1994 and on coil pack which uses one piece coilpack that contains the 4 coils instead of four separate coils.
So first u have to mark the coil wires coming from the engine harness, than cut up each connector to reveal the wires themselves.
The system I built so each coil gets a steady +, a steady – and a signal from the DME to spark each one at its correct timing.
Here's the engine harness side after cutting and marking the wires:

You can see the brown and green wires that are folded to the back of the bundle – these are the + and – as they are shared for all the coils in the new connecter, the only wires that are really separated and insolated are the command wires
Here are the command wires ready for soldering:

On the new plug side the situation is the same:

And

And this is how it looks like after initial soldering…

than we sould solder the green to green and brown to brown - to have the - and + for the spark's running and than wraping and insolating the wires is actually the most important part…
And that’s it – we're ready to use new coil-pack model
