THEMA: BR42 Fleishmann DCC

Hello,

I own a Br24 from Fleishmann. I have seen it's difficult to place a decoder in tender, because there is not many space in it. Someone has placed a selectrix decoder, wich is more narrow than other.

Fleishmann sells this loco digitalized. I supose they are placed their decoder in it, but ¿where?  Fleishmann decoders are bigger then SX decoders...

Can anyone tell me where FL has been placed the decoder in this loco?

Thanks in advance.

P.D.: Sorry for writting in english language. I'm spanish and I don't understand german language very well.
