Bee16hatch

I have an 95 eg hatch that I swapped with a b18c and when i get up to 6k, it cuts off. I know it can either be my dizzy or speed sensor but when I went to look at the sensor, the plug for the sensor was taped to the harness and removed my accident so I have no idea how the wires were connected. The 3 wires coming out of the plug are black, yellow w a blue line, and a yellow w white line but the harness has a black, orange and , black w yellow line wire. I know both black wires go together but where do the other two go too?
