Air Con Control Panel

[London 5]

Hope someone out there could be kind enough to confirm which order the wires go into the three pin connection on the top left in the photo.

Its from a E53 X5 2001 has rear aircon and max button on control panel

Cut a long story short I no longer have the BMW connection from the wiring loom so am plugging in one by one, hence red connectors

I have a Brown, Black and Purple&Red wire.

Appreciate anyone’s help, I can’t remember the order.

Thanks

Ben
