Immobiliser & ECU Help?

Hello

I am building a Haynes Roadster and using a 2005 NBFL MX5 1.8 vvt for the engine and running gear.

As my car is a fairly basic in terms of electrics I decided to develop a bespoke wiring loom rather than use the entire Mazda loom and all its various looms for electric seats, windows etc etc which are not required on my car.

However, we are having real problems now trying to reverse engineer the Mazda engine loom to simplify the loom down, the immobiliser and links to the ECU are causing real problems.

For seemingly obvious reasons Mazda have made this very complicated and difficult to defeat, but with me trying to do it for genuine reasons it makes it a nightmare to try and understand...

Therefore i was wondering whether anyone had detailed information or data (or any tips for that matter) on the interactions between the immobiliser system and the ECU to allow us to finish of the custom wiring loom?

Any help, diagrams, data, links would be most appreciated as this is starting to become a real issue with the build now.

Thanks for reading.
