Defender 300 engine loom bulkhead dash connector pinout

Does anyone know the pin out what controls the Diff lock light on engine loom in the master socket on bulkhead

Had to swap my engine loom got all the other connectors going all spot on other than the Diff lock light.

We suspect possibly one of the pins are maybe wrong in the new dash bulkhead master plug as diff lock definitely worked before changed it over

Put 12v up the loom from the diff lock & use a tester
