Series of universal modules for basic/simple use (when enought simple "copy lights" from car to the trailer) but also with advanced functionality ("buil-in logic", signalling some of status/malfunction, output for PDC steering).
It's characterised by legible connections of wires to the module (separate sockets for each group of wires) and easy to install (already connected socket with main harness).

There are available kits with all sockets - G7, G13-8 and G13.
