Does anyone know the circuit diagram for an ignition coil from a 2017-2020 NSX? I'm assuming it's going to be:

1. Trigger
2. Ground
3. Power

But I need to be sure before I wire up the harness.



Hitach part# IGC0094

The wiring from the harness connector's terminal side is:

1 - IG (IGN01) from junction connector (power)
2 - PG (Coil) from ground G101
3 - IGN01 from PCM

This would match with the way you listed for the ignition coil.

Thank you for the response. I found a diagram for them, which coincides with what you've said. However, it does not match the way I listed. Regardless, both you and the service manual have provided the proper wiring.

Looking forward to wiring these up!
