2d: Installing and Wiring Your Decoder
If you've followed our instructions so far, you should already know what this section covers because you’ve
already read the entire manual, right ? That being the case, you should also have accomplished the
following:
1:
You've verified that your motor is isolated
2:
You've traced your wires so you know where they all go
3:
You've figured out a location for your speaker
4:
You've performed any modifications necessary to fit the selected speaker into said location
Now, take a moment to study the diagram below, as it will be referred to often in the coming paragraphs
.
Okay, here comes the fun part. After grounding yourself, orient your decoder so that it matches the diagram
above in terms of direction. Next, locate the pick-up wires coming from the trucks (these may be the same
wires that you disconnected from the motor tabs when you isolated the motor). These wires will be tied into
the outer-most contacts on the ends of the decoder. The left rail pick-up will be tied into the output marked
TRK-L
(you'll note there are two tabs marked
TRK-L
, either tab will
work if you do not have individual rail pick-up on the front and rear trucks) the right rail pick-up will attach to
TRK-R
(again either/or will work if you don't have the provisions to do both).
Next, locate the motor + and – tabs. Tie the lead from the + motor tab to the left (motor +) tab on the
decoder, and the - motor tab to the right (motor -) tab.
At this point the locomotive should run on address, 3. You won’t have lights or sound yet, since we haven't
hooked them up.

The decoder will
now respond to

Caution: The speaker solder pads are close together – use
care to avoid a solder bridge between them- when
connecting the speaker wires!
