gnc switch key operation

Does anyone have any idea why the CNG switch keys have a negative ignition coil connection?

They use the negative because it detects that the ignition system is working and enable the passage of gas. If the platinum or electronic system does not work, it cuts the gas flow. I hope the explanation works for you. Luck

Does it mean that if, for example, platinum is closed for a certain time leaving the coil connected to ground, does the CNG key detect this and cut off the supply?

That same negative terminal of the coil is connected to the alarm. Could it be that if it trips it puts the coil to ground to cut the spark and the CNG then? I am investigating to see how to connect an electronic ignition. I want to make sure the current connections don't affect it.

Can be. Ground or cut the platinum connection. Look for the electronic ignition circuit and the alarm to be sure. You can turn on the car to activate the alarm to see what happens. Or if you don't turn on the car, turn off the alarm to see if it turns on. Comment what you did
