Okay so i finished swapping a 1jz with a w58 and auto soarer ecu into my original 5 speed sc300 this weekend. When i went to start it I turned the key to let it crank for a moment and then when i turn the key back or even take the key out the car keeps cranking. I wired the plug from the starter to the neutral safety wire and the other terminal to the positive terminal of the battery. How can i stop the starter from getting power after the move the key back?

 

Anyone have any ideas?
