Connecting the wires to the PCB

3.3 kΩ resistors, one per LED, are soldered to the common (corresponding to the blue wire of the decoder) near the PCB diodes ②. The other end of resistors is soldered to a copper pad which has been split in two ③ and ④, to which the blue wires are connected, the back LED’s ③ and the front LED’s ④. The green wire is soldered to the side of the corresponding tulip pin of the decoder connector ①. The white and yellow wires are soldered to the corresponding pads. The violet wire is connected directly to the decoder’s, thus without passing through the PCB, and is insulated with a heat shrink sleeve.
