3 sensors on bottom end?

[nickmk1]

Could easily be a stupid question but i couldnt find anything so ill have to come out with it, there is three sensors going into the bottom end. two about half way spaced equidistant and one near fly, possibly thinking its the crank position sender. The three sensors wires all meet at a connection point still very close to the block, and then go off from there. The one i believe to be a crank sensor i say this as its attracting some metal fur and as it meets the two other sensors at the same spot i thought it might aid the discovery of them!
Cheers guys!

Engine speed sensor aka crank sensor is to the right of the oil filter housing lookin at the front of the engine.

Speed sensor is on top of the gearbox casing as DPJ has said.
