ignition system

[Bonzo]

As per other posts

It looks to be a mixture of different components

Ford EDIS 4 modue

Vauxhall ESC module & coilpack

I believe that the ESC module is the Vauxhall equivalent of the Ford EDIS system.
I have no idea of how the two would manage to work side by side

The Ford EDIS module will run at 10 degrees BTC without an input signal from elsewhere
This is more of a limp home feature of the system & would not run the engine for peak perfomance without a signal from the likes of a Megajolt or the likes.

As said in other posts. Spark only, you'll need carbs.

Personally I would stick with Megajolt & EDIS if you want to run carbs
