Bruder low loader trailer extension

[Ed690]

Hi all ,I'm new in this hobby, nearly one year old 😁, and so far I have a Actros 3363 , whit a flatbed, and currently working on a bruder low loader trailer, extended and extendable. Have a look, any idea welcome.
I have some plans in my head, but maybe someone whit mare experience can help me : how can I run the function of the trailer (legs , ramps, extension) on the same transmitter of the truck , without wires, also trailer lights.
