This installation is for a HO-Scale Kato ALCO RSC-2 using a TCS WOW121-Diesel Decoder, AS-MB2-NC, KA4 Keep Alive™
and UNIV-SH4-C speaker kit by TCS.

HO-Scale Kato RSC-2 with the shell on 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.
Do this by holding the fuel tank with one hand and squeezing the shell on either side at the tabs highlighted below while pulling up.
Shown with the shell off and the original lighting board.
To remove the original lighting board, remove the plastic clip shown on top as well as the two screws that are holding the board down.
With these removed, lift it off of the frame. This board and lights will no longer be used.
The original rail pick up comes off of a common rail on each side, while the motor power is brought in via the metal clips.
These will need to be shortened and modified for the installation.
First, straighten and snip these metal leads, then solder a connection point to each and attach the new motor lead wires. Shrink wrap these leads to insulate
and protect against shorts.
Using hot glue or double sided foam tape, secure the front portion of the AS-MB2-NC to the frame, then screw the rear portion down to hold it firmly in place.
Do not over tighten this screw. Next, solder a low profile connection point to each track lead and solder a wire to each of these as highlighted above in red.
Branch each of these leads to allow connection to the two separate track solder points on the mother board.
Next, to mount the LED's we used (TCS 1417 two wired surface mount sunny white LED’s) as a replacement for the existing lights using a small dab of hot melt glue.
The front light tube was shortened to allow room for the speaker as shown below highlighted in red below with a small saw . Mount the KA4 into the top of the shell with double sided foam tape. Be aware of the fit and that it will rest behind the speaker and in front of the AS-MB2-NC when assembled. Solder the two leads to the AS-MB2-NC.
With the 2 LED's hot glued onto the light tubes you can connect the LED's to the AS-MB2-NC motherboard according to the included wiring diagram.
of the tube as well with satisfactory results. In doing so, white light LED output would be least affected, while non white LED output will be more affected by placement.
Insert the 25mm x 14mm speaker into the UNIV-SH4C enclosure, using hot melt glue, mount the assembly on the top, front
inside of the shell and solder the
leads to the AS-MB2-NC.
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 Kato ALCO RSC-2 is now WOWSound equipped and ready to roll!
