Left Side Marker Cable / Connector

[CLS70]

Hi -
Was replacing the LEFT (Driver) side marker and when disconnected the unit, the cable/connector sprung back and went /fell inside.
Have been unable to find a way to pull it out (can't see or feel it); tried fishing it with a grabber and also a twisted wire; have looked from inside the engine bay with no luck (removed the cover but there is no access).
Has someone ever replaced the fender or has an idea of where the connector / cables come from (e.g. from which direction) so I can focus where to search for it?
Thx
(p.d. pic is not my car, but is the same side marker I was installing)
