Thanks alot, but I don't have the original wire-harness so I can't see which one is red and black.
Any ide which one is pin-1,2,3?

take measurements of the resistances across the pins.  Pin3 will be the sheild so it will give no reading across the other pins.

It's matter. If you connect opposite you couldn't read rpm.
1pin +
2pin -
3pin shild
