I just purchased three new Bachmann engines: 2 truck shay, 2-8-0, and 4-4-0.  Unfortunately these are not plug and play so I am asking does anyone have (or can tell me where I may obtain) a simplified wiring diagram .  I have been in HO for 40 yrs. and have wired many NCE decoders.  However, I have never wired a receiver in a G guage engine, and I am really frustrated by looking at the wiring boards in these three G scale engines.  Thanks, Mike Phipps Sunset Beach, NC
