1.8K views · 43 reactions | Have you wondered how to connect a CurrentKeeper or Stay Alive to a 21-Pin decoder? Unfortunately, there is not room on our 21-Pin format decoders (TSU-21PNEM8, BLU-21PNEM8, or ECO-21PNEM) for a CurrentKeeper plug. You can use options like the decoder buddy. But, if you don't have one, you can still use a CurrentKeeper by soldering it directly to the 21-Pin NEM connector in the model. In this video, George will show you how. | SoundTraxx | Facebook
