HO-Scale Intermountain SD40-2W prior to installation.
In order to remove the shell, we must first remove the front and rear couplers screws highlighted in red above, the couplers and their housings.
With the couplers and their housings removed, the shell can be lifted up and off of the locomotives chassis. Above is a view of the shell removed.
Cut and remove the zip-ties that hold the wires in place and identify the wiring layout.
Be very carefully not to damage wires when removing the ties.
Remove the four screws as highlighted above in red, saving them for later.
Remove the original lighting board and being careful to preserve the plugs, unplug the connectors.
Utilizing the original screws, attach the IB-MB2 motherboard to the chassis, then plug in the original connectors onto the motherboard in
the appropriate locations according to the included wiring diagram. Unscrew and hold onto the screw highlighted above in red on either side of the speaker enclosure. We will not be reusing the original speaker or enclosure, but we will be re-using the screws.
Shown with the speaker removed.
With the 35mm x 16mm speaker inserted into the IB-SH1 enclosure,
using the two original screws, attach this assembly to the frame.
Plug in the WOW121 diesel decoder. Reattach the shell taking care not to foul any wired during installation. Your Intermountain SD40-2W
is now WOWSound equipped and ready to roll!
Finally, place the locomotives shell back on and reinstall the front and rear couplers and their housings. With this installation, you can independently control the front and rear headlights and marker number board lights.
