HO-Scale Kato AC4400CW shown prior to installation.
To start off this install, we must first remove the front and rear coupler screws highlighted in red 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.

Remove the wires and the two screws highlighted above in red and remove the lighting board from the chassis.
With the original lighting board removed, trim, tin or lengthen the wires as necessary.
To make a new motor connection, first trim off the metal motor pickup tabs as shown above. Solder a connection point to each of these, attaching the new leads,
then insulate these with shrink tube insulation. We used small lengths of TCS 3/32" and 3/64" shrink tubing.
Attach the AK-MB1 to the frame and solder the motor and track pickup wires according to the included wiring diagram.
Next with a soldering iron, carefully remove the two existing LED's from each end of the original lighting board.
Take the original rear LED and using a small pair of pliers, bend the ends out as shown to fit onto the front of the AK-MB1. This will become the front lights.
Solder it in place as shown above facing into the end of the light tube.
To allow a space for the speaker assembly, remove the rear light tube from the shell and using a small mitre saw,
trim it down to about 1/8" from the face as shown above. Reinsert this back into the shell.
Clip the lead lengths of the original front LED and then solder new leads to it, insulating them with shrink tubing as shown above left,.
Using a small amount of hot melt glue, mount this into the top rear of the shell as shown above against the trimmed light tube.
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.
With the 25mm X 14mm WOWSound speaker inserted into the UNIV-SH4-C enclosure, using double sided foam tape, securely mount this assembly into the rear top of the shell.
Solder the rear LED and speaker wire leads to the AK-MB1 according to the included wiring diagram.
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 AC4400CW is now WOWSound equipped and ready to roll!
