This installation is for a HO-Scale Bachmann GP30 using a TCS WOW121-Diesel Decoder, IB-MB1-NC with Keep Alive™
and UNIV-SH1-C WOWSpeaker kit.

HO-Scale Bachmann GP30 prior to installation.
To start off this install, we must first remove the two screws indicated above that are located underneath the fuel tank.
Next, remove the two screws on the frame under the tank as indicated in red above.
With the board off, take note of the wiring to be sure to replace it in it's correct location. At this point, remove the screws located at each end of the
original lighting board as highlighted above in red. Unsolder the wires and remove the board.
Shown with the original lighting board removed. Trim, tin or lengthen the wires as necessary.
Underneath the locomotive chassis are three hardwired yellow capacitors marked with “104” highlighted in red.
Carefully remove these. It is not necessary to remove the other two green components with color stripes on them.
One top of the frame there are two metal threaded standoffs. Trim these off with cutters and file smoothly to allow for the installation of
the IB-MB1-NC motherboard.
Using double sided foam tape, mount the IB-MB1-NC to the top of the frame and solder the motor and track leads in place.
With this done, solder the speaker wire leads to the IB-MB1-NC motherboard. Insert the 35mm X 16mm speaker into the UNIV-SH1 enclosure and using
double sided foam tape, mount it to the frame as shown.
NOTE: You must be very careful to avoid getting glue on the speaker cone. Glue on the speaker will ultimately cause it to produce no sound and fail.
Taking the original lighting board, remove the LED’s from the board. Be mindful of the polarity of the LED’s. The cathode has the flat side and you
can see a larger flag shape part in the LED. The other side is the anode, it connects to blue (+12v).
Solder the LED's to new wire leads and using a dab of hot melt glue, place these on the the light tubes.
Solder the lighting wire leads as indicated in your wiring diagram to the IB-MB1-NC motherboard.
You can now plug in your WOW121 decoder.
Lastly, in order to keep the wires neat and prevent possible shorts, lace the wires into a bundle using lacing cord, which is a wax impregnated string
used for wire bundling and making harnesses. There are many choices of lacing cord available from Digikey www.digikey.com.
We use part number 802534B BK032-ND
Now you can close up the locomotive and reinstall the coupler assemblies. Be sure to be mindful of wire routing and reassembly of the shell as to not damage
or foul the installation. Your Bachmann GP30 is now WOWSound equipped and ready to roll!
