Hi, sorry if this question has already been covered, I don't visit this forum very often.
I have purchased a couple of locos that require 21 pin decoders. I've been looking at these decoders but as it happens I usually use 8pin and have a small stock of these. I have come across adaptors that claim to convert 8 pin to 21 pin - so, my question is; are these adaptors any good and is the functionality preserved?
I'm not interested in sound but I have the Dapol railcar which has a few lighting functions.
