Mike,
Thanks for the picture, it really helps. You need one more wire to get the loco to reverse. Solder one end of a wire to the end of the green wire connected to the center terminal. The other end of the wire goes to the second terminal of the e-unit. See the red line I drew in your picture.
The hyperlinks I inserted do open up properly, and the service manual pages open in .pdf format. Make sure your browser is able to display .pdf files.
