DH163 wiring of LED's on Athearn Hello all, I am wiring my Athearn loco with the DH163 decoder with the wires. Everything works fine with my DCC. The problem that I am having is wiring LED's for the front and back. There is the common blue wire from the decoder, the white for the forward light, and the yellow for the rear. The resistors are 1K. The LED's are 5mm in size. Question: The short LED lead is the (+), and the long is the (-) . The blue common wire - which must be used for the switching from front to rear light with the change in loco direction...which lead on the LED should connect to which lead on the blue common wire (+)? The resitor should be on the white and the yellow leads, right?
