Thanks for the information.  I am new to dcc and did not realize there was a dummy plug with a socket underneath.  I could have ordered the easy install decoder.  I will use the idea from the article to use the dummy plug.  I have a couple of extras as I followed the directions from a Model Railroader article on modifying the 2-8-0 for Central Vermont, and the two that I clipped and glued the reversing mechanism as instructed went out of quarter within a couple of hours of operation.

I purchased an ez decoder without the plug so I could hard wire it to the circuit board of a spectrum 2-8-0 that does not have a plug.  The directions are only for a circuit board with a plug.  How do I wire the decoder to the older non dcc circuit board?  I thought there might be a diagram showing where to solder the wires. 
Anyone know how, or where there is such a diagram?
Thanks jsharger
