HO-Scale Bowser RS-12 prior to installation.
To start off this install, we must first remove the front and rear couplers and their housings. Once that is complete, the shell will lift off of the chassis.
With the shell off, we can now remove the factory light board so we can attach the KA4 Keep-Alive™ to the underside of the board. First disconnect the wire harnesses from the board.
Once the wire harnesses are loose, the factory light board can easily be unscrewed from the motor mount.
Tip the original lighting board up on its side so you have access to the bottom of the board. Solder the black with white stripe wire from the KA4 Keep-Alive™ to the side of the R4 resistor as shown in the image below. Now solder the blue lead from the KA4 Keep-Alive™ to the 12v+ Common hole from the 8-pin NMRA plug as shown below.
With the the ground wire connected, replace the original lighting board and screw it back down to the plastic holder.
Mount the KA4 Keep-Alive™ on top of the rear gear tower using hot glue or double sided foam tape.
Next remove the factory provided speaker enclosure.
Solder the 2-Pin JST connector with wires to your speaker, mount the WOWSpeaker in the enclosure provided with your WOWKit, and use two of the screws from the original speaker enclosure to mount your speaker and enclosure in the frame.
Finally, plug in the WOW121-Diesel decoder (with the pins from the lighting board passing up through the bottom of the decoder and into the connector), replace the shell, reattach the couplers and your WOWSound equipped RS-12 is ready to run!
Be sure to be mindful of wire routing during reassembly of the shell as to not damage or foul the installation.
