Below is a wiring guide for the ESU 58821 LokSound 5 DCC Direct decoder. These are the perfect decoder for hard-wiring into a variety of locomotives across all manufacturers. If you plan on using AUX5 and AUX6 for LEDs, you must use a resistor rated between 470 Ohms and 2.2 kOhms wired in series with the LED.

The ESU 58821 comes as a decoder and motherboard assembly. In the below image, you'll notice two pieces. The larger, bottom piece is the motherboard. The smaller, top piece is the decoder, which plugs into the motherboard via the Next18 connector.
