just this,
why not reverse engineer it>?'
the IGBT , (ignitor) in the early cars had A resistor from gate to source, 150ohm? (holds charging coil off by default)
this prevented burning the coil of if one opens the gate connection, (obvious)
use a dmm , meter, in ohms mode measure it.

I do not have a 1996 1.6 16v ecu to scope the igniter driver output (orange wire) unfortunately. I’m just not sure if the signal from the ecu is 5v or 12v to pulse the igniter. I will check the resistance between gate and source. Currently I have megasquirt set up to pulse a 5v signal to the igniter gate, but it’s not operating the gate. It may be the internal resistance you mentioned is too great for my signal to overcome.
