Trouble Finding Correct Crank Sensor

I just picked up a 2005 S60 2.5T. It has a salvage title, so I'm prepared to have issues. Already, those have begun. Cranking no start. Gas on plugs (all of them) so probably no spark. Checked codes and I got a code for crankshaft sensor. Makes sense to me. Go to order one and it doesn't match the one in the car (pulling it from on top of the bell housing below the air box). Every parts place that looks this car up pulls up the same incorrect sensor (31331765). Called the dealer and parts guy says my vin points to the aforementioned sensor. Mentions another part number for same car different vin. I look that one up (31331754) and looks even more wrong. I'm starting to suspect the engine was swapped. 1 problem here is I can't find engine vin tag to track down right part. Timing belt cover says B5254T2. Transmission says 55-51SN. I think these both seem correct. I've looked up other cars that use this trans but none of the crank sensors match what I have. Please help.

Posting pic of sensor I pulled. Has only 4E27 for numbers. 2 pins.

You'll get that from time to time. The replacement part will be an updated design that may not look exactly like the original. I wouldn't worry about the 90 degree bend to the harness connector. It was probably a change to reorient the plug/harness to allow for more clearance when performing service to something else in that general area.

I'm an idiot. Apparently that's the speed sensor. Still looking for the Crankshafter sensor location. Will post in case someone else has this confusion.

On the transmission bell housing where it mates to the engine, midway between the camshaft position sensors, directly below. You may have to remove/reorient the intake air pipes to get clear access to it. The google gods found this nice little sketch on imgur:

The diagram shows a sensor for older white blocks with a short wire leading out to the connector. On the newer ones the sensor is in the same exact location though.

Yup! Found it. Turned out to be the fix to no spark issue as well. So yay!
