please excuse this really stupid question - im sure there s a sensible answer to it - why does someone need to fit this to a loco with a 21 pin socket? ... why not fit a decoder with 21pins on it into the socket? ... i know im missing something here - probably a brain but id really like to know!.
who fits 21 pin sockets, iv only ever seen 6 and 8 pin sockets. is it for extra functionality having so many connections?
thanks and sorry for the stupid question - im still learning about all this - its kinda moved on a bit from the 3 wires of zero-1!
