A friend is trying to add a decoder to a Large Scale Bachmann Heisler. I have looked through the online parts/manuals and cannot locate a manual to understand the wiring. I will put a picture of the board below. Can someone please help me identify the wires to add a decoder and/or possibly find the manual online? Also, does anyone know if this loco has LEDs or incandescent? Thanks
