Breaker recommendations?

[shirt]

Hi all,

Just wondering if there is a decent breaker in uk I can source the internal harness for a headlight unit, 2016 panamera.

Took the back off the existing one and there are multiple failures of the wiring insulation. Everything else checks out ok so seems overkill to have to replace the whole unit. Only I can’t source just the wiring locally (UAE).

Any recommendations would be helpful, thanks
