Got a new crankshaft sensor wiring harness for cause the old was falling apart, now the question is what wires hook up to the new wiring harness? It’s A B C on the harness but I can’t figure out what colors go to what letter here is a picture of the wires

But his are brown tan and beige.
Actually the top looks purple and the bottom yellow. At one time anyway.
Because of their location I'd highly recommend soldering them and using marine self sealing 3 to1 shrink wrap. Lots of of and road water spray right at the front of the engine that low. On the LS engines they moved them to the rear above the starter to get away from all that.

Chevymec is correct on colors. If you want to confirm which wire is which due to color fade or something; pin A should have power from ECM IGN fuse 10, pin B should have ground, then of course your left over wire for the sensor signal will go to pin C. You can check A and B with a test light or voltmeter. There is a chance that fuse is blown if your wires touched each other with the key on.
