As usual, "BIG" came in here and didn't read--or LOOK. If HE would have, he'd seen that the starter solenoid/ contactor on the OP's starter HAS ONLY ONE small stud. There is no way that the OP could have incorporated the NSS system with that contactor "as it sits."
How do you know that is the correct solenoid? It might have been changed and the wrong one used. It is entirely possible the sol on the car is correct for a vehicle with a standard shift. It is not correct for a Canadian build with an automatic.
