You have all missed the question I asked. I need to know which two wires from the four wire plug go to the motor in the engine or which two go to the lites. Not all the color coded wires from the engine match the color coded wires from the decoder. I have already installed the speaker and the decoder. I would like to do this without removing the shell from the engine. Thanks, Tim

I have a spectrum 4-8-2 heavy mountain that I'm going to install a tsunami sound decoder in. There are (2) plugs that go from the tender to the loco. One is a (2) wire plug with red and black wires that i assume are the power from the loco wheels. The other plug is a (4) wire with a orange, lite brown, yellow and red wire. Which (2) go to the motor and which (2) are the lighting? I couldn,t find any info in the paper work that came with the loco or on the Bachmann web site. Don't want to disassemble the loco to find out. Doesn't look like a fun job. Thanks, Tim
