Thanks guys! I'm happy you like it!
I like your signature Claus, I agree with you!
Bigdogrod, the kit from Sstronix is the wireless "module" added to the Tamiya mfu for connecting my two trailers without any wires between them. When installed, it works exactly the same way than before. It's also a power source for adding lights either on tractor (with add-on interface) or trailers.
The module itself is relatively small compare to mfu but the require place must be verify if you don't have space in your cab...
Did I answer your question? Don't hesitate if it's not
