Wiring help, Micro Dynamics electronic module IGN07

Hi, I have the Micro Dynamics electronic module from the 80's I believe, the engine is a Ford Crossflow 1.6. I must admit when it comes to electrics, I'm useless, hence this post I want to know where to connect the ignition wire from the ignition switch to and to which terminal do I put the the blue wire from the cold start to on the solenoid. The solenoid is a cold start solenoid.
All this was running on the engine prior to me buying it in 2019, it hasn't been installed in the car and I have since forgot where what connects nor got any idea.
I would like to keep everything that I have and try and make it work - unless there is anything out there more modern and less complex (which I doubt).
Thank you for looking.

after a quick bit of searching, I found

the second image suggests the cold start/ ballast resistor are not required, and should not be installed.

Hi, Thanks for this I have this document, I also have this Document
this says that a ballast and cold start should be used if the engine is tuned I know the engine has a mild tune and the other thing is that the engine was working with this setup.

it comes down to what coil you are using.
ballast systems use a 6v coil, and 'boost' it to 12v supply during start-up
non ballast systems us a 12v coil at all times.

I suspect the 'cold start adaptor' is just a diode.

but it using a good battery, on a reasonably warm day, it should not matter either way.
