Dance radio replacement 12v ignition connection

Hi

I wanted to replace my standard Dance radio headunit with a standard 1DIN headunit. I needed a extra fascia plate with cable adapter.

I needed to find the connection in the Skoda Fabia socket that only give 12v when the ignition is turned on. Use a multimeter the read out the voltage. But none of the other connectors only gives power when ignition is on.

There is 1 red cable with constant power, a black mass cable.

A brown/orange and brown/green cable. Tested both and they give nothing when ignition is on. 

Does anyone know what connector I need to use in the black part of the Skoda Fabia socket?

Thanks a lot.
