My crankshaft position sensor connector broke off I bought a pigtail but, all the wires are white I have no idea how to reconnect to my original-colored wires it's a 3-wire connector.

That is done so that they can use that same connector for anything that requires 3 pins. In your case the three colors are Pink with a 12-volt feed on pin A, then a Purple that is a ground into the ECM on pin B, and lastly a yellow wire that is the sensor signal. The connector image is looking into the connector with it unplugged. The connections there need to be good. I use individual non-insulated crimp connectors and adhesive lined heat shrink normally like in this video:

You can also use the combination crimp with heat shrink on it like the ones in this video:

Both work well as long as you don't damage the insulation.

Hold up the connector so you can look into the face of it like the attached picture above, that shows you ABC.
