Hi all!
First I’d like to introduce myself. I’m a modeler from Poland and after a long brake I’ve decided to return to hobby for real. For my first project I’ve chosen the stuka zu fuss and now I have a huge problem with this project. I have been surfing the net for weeks and nothing….  I couldn’t find any interesting photos referring to firing system. I’m really exhausted and confused, It really makes me crazy. Please help me!!!! Now I will try to explain the problem… 
All I know is that each rocket was plugged to the thin wire (number 1.). So we have three thin wires on each side. Each thin wire was plugged to the thick one (number 2.) which was attached to the inner side of the hull. 

Now the problem begins. Where the thick cables end. And the second question. How the firing remote looked like (any photos) and how it was connected to the firing system. 
I would be very  happy if you could help me.
P.S. Sorry for my english
Best regards
Michal
