21 Pin / 21 MTC Male to 21 Wire Adaptor

Uses include fitting a Hornby TTS decoder to a Bachmann 21 pin loco for example.

Remove the original 8 pin plug from the decoder wires and solder this item on in it's place. This is more height efficient than using a 21 to 8 pin plug adaptor which can sometimes be too hgh to refit the bodyshell.
