First, remove the coupler box screws and the coupler boxes from both ends of the locomotive.
Now, extract the two screws on either end of the fuel tank which you can see highlighted in red above.
With the couplers and under truck screws removed the shell should lift right off the chassis.
Remove the original lighting board from the chassis and remove the wires from the board tabs.
Next, we will prepare the speaker housing. Remove the screws holding the speaker in place.
Next, mount the 28mm Round WOWSpeaker facing into the speaker housing. This may seem counter-intuitive, but this permits the speaker wires to remain on the outside of the housing allowing for a solid seal all the way around.
Next, mount the GEN-MB1 on the motor just like the original lighting board and begin wiring it up according to the wiring diagram in your motherboard manual.
Solder in the lighting connections from the shell and install the WOW121-Decoder to complete the wiring of your installation. All the original 1.5volt bulbs supplied with the Athearn loco were used. The "FL" solder pad is the forward 1.5v solder pad for the front lights. The "RL" solder pad is the reverse 1.5v solder pad for the reverse lights. The ditch light bulbs are connected to the solder pads marked "1", "2". The solder pad marked "1.5V" is the common power source for the bulbs. This motherboard can be configured for LED operation as well, the mother board has built in current limit resistors for LED use. Consult the wiring diagram for LED use.
Finally, you can replace the shell (it should slide over the installation easily), screw the shell in with the screws beneath the trucks, replace the fuel tank, and replace the couplers on the engine.
Your WOWSound equipped engine is now ready to run!
