On the side of the throttle body the side you would see when looking into the engine bay as normal the is a three pin plug my top wire of that plug as snapped from the plug can't be fixed what does this top wire do I have spare loom just haven't changed it.with this wire not connected has caused no running problems either.

Hi
Its probably the Throttle position sensor plug
pin 3 goes to earth
pin 1 and 2 go back to ECU

Depending on what cable/connection is broken is wont read throttle closed, open or a resistance value on position of butterfly valve.
3 pin plugs with pins can be bought easily, but if your local I may have a plug and the pin removal tools
