Hi , I have recently purchased a Sonic models 56XX in N gauge and was surprised to see that it required a right angled decoder , my system makes use of Railcom so I needed a decoder that had Railcom and the only one I could find that fitted the bill was the ESU Lokpilot Micro 5 , on receiving the decoder I was again surprised to find that it has 5 wires attached to it which I guess are for functions ? , I have no need of any functions on this Loco so can I safely snip of these wires as close to the circuit board as possible ?.
