This was performed by our friends from DCC Xpress installations a HO Scale Life Like Proto 2000 0-8-0 Steam using a P2K-MB1 motherboard, WOW121 steam decoder
and UNIV-SH1-C WOWSound kit. They offer high quality WOWSound installations for a flat rate complete with free return shipping!

Important Soldering Tip:
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157

HO-Scale Life Like Proto 2000 0-8-0 Steam shown prior to installation.

    To start off this install, we must first remove the four screws highlighted above.

With the screws removed, while gently pulling outwards at each end and along each side of the frame, lift the shell off of the frame.

The Life Like Proto 2000 0-8-0 Steam tender shown with the shell off. Unplug the 8 pin connector from the original lighting board and move it off to the side.


With the connector loosened, remove the two screws highlighted above in red and remove the lighting board from the chassis.

Attach the P2K-MB1 to the frame with the original screws. Plug in the original 8 pin connector to the new motherboard.

With the board on place, the LED that is furnished pre-set on the board will need to be bent outward slightly to direct the light into the light
tube found inside the rear of the tender shell.


Next, in order to create a place for the sound the escape, using a small drill, drill in a series of small holes into the coal load at various angles as shown above.
Once the tender is back together, these holes are visually inconspicuous, but aid greatly in the volume and quality of the sound output.


With the 35mm X 16mm WOWSound speaker inserted into the UNI-SH1-C enclosure, mount this assembly to the frame as shown above.On this install,
we layered a couple of trimmed to fit pieces of plastic, using double sided foam tape to 'float' the speaker assembly inside of the tender under the coal load.
We then used a small strip of hot melt glue to hold this in place.

If your speaker enclosure installation covers the portholes on the enclosure, we recommend adding new port hole(s) similar to the original porting. Be sure that the new portholes are the same size and amount of the original and are vented freely into the locomotive We have found introducing a port of the correct size greatly increases the volume and sound quality of the installation. Too much or too little porting decreases the sound quality.

NOTE: You must be very careful to avoid getting glue on the speaker cone. Glue on the speaker will ultimately cause it to produce no sound and fail.
With this in place, solder these wire leads to the motherboard according to the included wiring diagram.

You can now plug in your WOW121 decoder.

Now you can close up the tender and reinstall the saved screws. Be sure to be mindful of wire routing and reassembly of the shell as to not damage 
or foul the installation. Your Life Like Proto 2000 0-8-0 Steam is now WOWSound equipped and ready to roll!

Other solder tips: When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
