In preparation for installing DCC+sound into my loco, I prepped my CF7 today. To kind of organise the inevitable wire bundles inside the loco, and reduce them, I used a small piece of 'vero board', also known as experimentation board for electronic projects. On this I've soldered all the resistors as well as two of the leds (one for the front head light and one for the roof beacon). From this board, two wires run to the rear of the loco to the rear led, and a bundle of 4 wires come down from this board to the DCC decoder. This way the installation is a bit cleaner and organised. In addition this small circuit board (which just fits in the roof of the cab)was covered in black electrical tape, and stuck in place with a bit of double sided tape. This way it will prevent light from the LED's to leak into the cab.
A picture of the installed pcb covered in tape can be seen here. (also one of the see through roof fan grilles is just visible).
