Adapts many 21-pin decoders for a hardwired install!
THe 21-HWM is a circuit board with a NEM660 (MTC21) plug with solder pads to connect wires. The male 21-pin plug may be used to plug into a 21-pin decoder socket such as the WOW121 or EU621. The decoder can then be hardwired or used with a plug-in harness. The 21-HWM is great for situations where space is limited and a full-size motherboard cannot be used.
NOTE: The header pins on this adapter board are a little short of both ESU and Soundtraxx decoders, but they will work.
To solder wires to the provided pads simply:
- Tin each pad with a SMALL amount of solder
- Strip the end of each wire and tin it with a small amount of solder
- Solder the wires in order from top to bottom as listed:
