The MK7 Ford Fiesta ST has a similar cost saving measure as the MK3 Focus RS: only having one boot / trunk light and then a plank on the other side.

This harness enables the addition of a second light!

Featuring an OEM style fully taped wire and the same 501 connectors found in the car from factory, the finish on this harness / loom both looks like an original part but also is very easy to connect together!
