clutch position sensor

I bought a 2006 Maserati Quattroporte that had been to a butcher shop (bad shop) things were missing such as the clutch and throw out bearing and the clutch position sensor...I have gotten all the parts but they cut the wire to the sensor and I have no plug to plug the sensor into..the wires...

So, my 05 Quattroporte broke down the other day all of a sudden. The electronic system failure and transmission failure lights came on, and the power went out. I am told it may be a Clutch Position Sensor. Does anyone have any experience or advice on this? Also, how much does this cost...
