GT40 Engine Start Procedure & Protocol

Just a question to make sure I get this right, what is the correct procedure (including dashboard light indicators) for starting the car?

Correct me if I'm wrong with the following steps:

1. Electrical system on via key switch. At this point, what colour light is correct to indicated "engine off" state?

2. Fuel pumps on.

3. Engine start via starter pushbutton.

What I want to know is at what point should the "engine off" light turn off.

Thanks in advance!
