I bought this car, and somebody put a pigtail connector on the crankshaft position sensor. The wires that terminate the harness are green, red, and red with black. The pigtail wires are black, blue and purple. Can you tell me what color wires to connect, please?

Here is the wiring diagrams for the sensor, no connector view for some reason. So you will have a 50/50 chance (both out side wires) unless you can read the terminal numbers on the connector. Check out the images (below).

That diagram doesn't jive with the wire colors that terminate this harness. I have red, green and red with blue stripe for the wire options leading to the sensor connector.
