Soft top rear window defroster broken connection

  1. My model of MX-5 is: _Mk 3
  2. I’m based near: _Winchester Hants
  3. I’m looking for technical help or recommendations on: __reconnecting soft top rear window defroster

One of the wires to the white connector which activates the rear window defroster on my soft top has broken, no doubt as a result of the top being put down as much as possible in the summer. I tried to mend it myself but it is extremely difficult to get too and I could not remove the old wire from the connector. Halfords were not help and neither were my Mazda main dealer who did not have a new connector.
Next stop is my local garage I guess but has anyone else had this problem? Advice gratefully received,
