HO-Scale Dash 8-40CW shown prior to installation.
To start off this install, we must first remove the front and rear coupler screws highlighted above and their housings.
With the couplers removed, while gently pulling outwards at each end and along each side of the frame, lift the shell off of the frame.
Take care to release the handrails as you lift off the shell so they don't break.
The Dash 8-40CW shown with the shell off. Unplug the wires from the original lighting board and remove it from the chassis along with the dummy speaker plug.
Shown with the original lighting board removed. Take note of the wire functions.
Attach the AK-MB2 to the frame and plug in the motor and track pickup wires according to the included wiring diagram.
Using double sided foam tape, mount the KA4 as shown to the frame and solder the leads to the AK-MB2
according to the included wiring diagram.
Insert the speaker plug into the left side frame opening and secure it with the metal clip, then likewise insert the 32mm WOWSpeaker into the
opposite opening, secure it and solder the leads to the AK-MB2. The above right photo is showing the locomotive in reverse orientaion for this purpose.
You can now plug in your WOW121 decoder.
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 Dash 8-40CW is now WOWSound equipped and ready to roll!
