12. Reinstall the motor in the frame. Be sure to
insert the drive shaft into the flywheel before
reinstalling the screws for the motor mounts.
Install the driveline removed in Step 6 and
replace the retainer clip to hold the worm gear
and the other driveline in place.
13. Using double-sided foam tape, mount the
decoder to the top of the motor. Be sure the
M+ wire that was added in Step 11 comes out
on the proper side of the decoder to attach to
the M+ tab on the decoder. (Photos 15 and 16)
14. Solder the wires for the track pickup and motor
to the respective terminals. There is only one
track negative (-) lead attached to the frame.
Solder this to the proper tab.
15. Test the model for proper operation by placing
it on the mainline and running it in forward and
reverse. There will be no lights or sound yet.
Correct any problems now.
16. The speaker for this installation is a small oval
speaker. Start by soldering two 6”pieces of
30-32 gauge wire to the terminals on the
speaker. Since we are using only one speaker,
polarity is not important. (Photo 17)
17. Next, cut the sides and top for the styrene
baffle following the template at the end of this
document. Using liquid plastic cement, secure
the styrene pieces around the sides of the
speaker. (Photo 18)
18. Thread the wires for the speaker through two of
the mounting holes in the speaker frame, and
then cement the top on to the assembly. File
or sand the joints smooth for easier handling.

19. Secure the speaker assembly into the top of
the model facing upward (if the radiator fans
are open; face down if fans are closed). Secure
in place using silicone and allow to fully cure
before moving on.
