10. To install the speaker, start by soldering a
3”piece of 28 gauge wire to each speaker
terminal. (Photo 8)
11. Lay the speaker face down on your work
surface. Use the baffle template located at
the end of this document to build the walls of
speaker baffle from the sheet styrene. Drill two
small holes in the indicated side big enough to
allow the speaker wires to be threaded through
it. Cut the pieces as indicated and attach them
to the sides of the speaker using liquid plastic
cement. Thread the wires through the holes.

12. Next, cement the top of the enclosure to seal
the speaker baffle completely.
13. Seal the four holes on the front of the speaker
and any gaps with silicone. Allow to fully dry.
14. Solder the wires to the S+ and S- terminals (5
and 6) on the decoder. (Photo 10)
6. Install the TSU-GN1000 using the mounting
tabs for the factory circuit board. Place the
decoder over the mounting tabs and gently
press down. (Photo 6)
7. Attach the track pickup (1, 4, 9, and 12)
and motor (7 and 8) wires to the correct
tabs following the diagram at the end of
this document. We recommend that these
connections be soldered. After soldering, you
can use the plastic clips removed in Step 3 to
cover the connection.
8. Test the decoder for operation by placing the
locomotive on your mainline, selecting address
3, and running it in both directions. There will
be no lights at this time.
9. Next you will need to fashion a support for the
speaker assembly. Cut two 36mm pieces of
2.5mm strip styrene. Silicone into place over
the rear driveline of the model. Set the model
aside and allow to fully dry. (Photo 7)
