Cam and Crank Sensor question

[B3M2W5]

I have an M50tu that was taken out and replaced by an S52. It happens to be a budy of mine and he used all of the sensors and miss. stuff to convert the S52 back to OBD1.
There for i am missing a few things. Like the Cam and Crank position sensor. I happen to work at Oreilly Auto parts and have goten what is listed as the Crank position sensor for the M50 from 93 to 95 wich i am asuming is Vanos.
Any way i picked up the part from work and now that i am back at home have realized that i have no idea where it goes. the motor i have is about as bare as you can get with out taking the head and the alternator off every thing else is off the motor still yet to be put on as i have had to buy every thing for this engine agian.
If some one could plz let me know where the Crank position sensor is located on these motors, and if any one would happen to know the part # for the Cam position sensor.
I would really apreciate it.

Crank position sensor is right above the front crank pulley on the timing chain cover. On the s52 it is on one of the sides of the block near the bottom and rear, intake side I believe. Not sure if you have to re-locate it for OBD1 conversion or not.

He's right on. You leave the old OBD2 one where it is to block the hole, but the new OBD1 CPS sits directly over the harmonic dampener on the front of the motor, on the T chain cover. There's a right angle flange with a hole in it the diameter of the sensor. It slides in from the top & secures with small bolt.

Ok so on my M50 it should be on the front of the motor near the hamonic balencer.
