This question is most probably best answered by John or George. Am upgrading a MT-6604 GP-9 (protosound) to PS3. There are too many, long, wires not used in this installation and I desire to eliminate as many as possible so they do not have to be crammed up on top of the boards. There is no smoke unit in this diesel. So I removed the following wires from the 40-pin connector: for the smoke fan (#16,18, 21) and for the smoke heater (#8,10,14). Question is - can I safely remove the smoke control wires 15 and 19 (partial) without causing a problem. There is no sense in bundling up wires, etc. that are not being used and take up a lot of room on top of the board set.
Thanks,Bruce
