I am installing an 04 GTO motor and I have one plug that I don't know where it connects. It's on the passenger side and has 3 green wires.

Maybe the crank sensor? Above the starter.

Yes, it was the crank sensor. I couldn't see it behind the starter.

Thanks for the help, hopefully I will be starting it today.
