Help: Broken wires 2007 Alfa 147 2.0 Engine Pair-Blue/Yellow

[Dean1407]

Hi all,

Was replacing the crank sensor and accidentally pulled out a pair of wires from the back of the engine.

Pair is just to right of crank sensor and connects to the Engine ECU; tried to add some photos but that must be above my skill level 

I think it is the K46 RPM Sensor but cannot find out where it runs to at rear of engine.

Anyone out there able to help?

Thanks,
Dean
