A friend has an NW 611 2-rail loco/tender from about 1997-98. He wants to locate/understand all the wires inside the loco. His hope is to integrate an updated control board in the tender. There are 4 wires running to the tender (red, white, yellow, black as pictured). Can someone please help me identify the wires and understand if they can be used to control the train (motor,lights,track leads etc).
