e28 M5 Pick - uP

[ISADORE]

Good Day Gentleman,i recently bought myself an e28 M5,the car did not have a motor in and after a long search a managed to get a Motor.The car had it's clutch & pressure plate but the flywheel was missing.I also have the car's original gearbox.The wiring harness was still intact including both pick-up sensors mounting onto the gearbox.We've tried to start the car but could not get any spark on the motor.I do not know is it because i used a flywheel from an e12 528 which has a small pick-up the size of bearing ball on the flywheel.

I do not know what the flywheel of an M5 looks like and would really appreciate if anyone could assist.
