Sorry just a quick one, the 4 wires from the distributor on the N/A engine
1? NE
2. NE- : these are crank trigger input.
3. IGT: this is the spark event request sent out by the ecu to fire the coil.
4. IGF: this is a feedback signal sent by the coil back to the ecu when a successful spark event has took place. Essentially if the ecu doesn’t receive a IGF signal back from the coil for ‘x’ amount of times it’ll log a fault code.
ive marked them above numbered 1 to 4, number 1 where does that go as you mentioned 4 wires which it has but i only read descripti
