If it is, these were mostly used in clubman minis.
Mk2 S and mini K used a 6-gang joiner like this:

The 13H7779 blinker switch comes with the clubman terminal block. For originality, the switch stalk is almost identical but to fit to a Mk2S or K, the wires need to end with bullet terminals which push into the red 6-gang joiner.
Some of the wires used to control high/low beam at the blinker switch have been cut by the factory for S and K application.
