Installing decoders can vary from simple plug in procedures to very challenging hard wiring projects. In this video I want to share with you the process I followed installing a SoundTraxx Econami PNP decoder in a Stewart F3A diesel that I wrote about in my DCC Corner column in the January 2020 Model Railroader magazine. This is a fairly easy hardwiring project that doesn't require a lot of experience or advanced soldering skills. In the video I used an 11x15mm sugar cube speaker and enclosure from Tony's Trains, 3/32" and 3/64" heat shrink tubing from All Electronics, and the SoundTraxx ECO-PNP diesel decoder. The LEDs are 0805 surface mount golden white with 1000 ohm resistors purchased on eBay. As you can see this is a long video which covers the entire process step by step.
