*****NOTE: In some versions of these models, the interior varies slightly, changing the space available for an install. For this reason, there are three different versions
of installs listed on our web site. PLease review and slelect the most appropriate version for your particular model *****

This installation is for a HO-Scale Life Like Proto 2000 E8/9 Locomotive using a TCS WOW121-Diesel Decoder, AS-MB2 NC Motherboard,
KA3 Keep Alive™ and UNIV-SH4-C WOWSpeaker kit.

This was performed by our friends from DCC Xpress installations.
They offer high quality WOWSound installations for a flat rate complete with free return shipping!
You can find them at: www.dxinstalls.com

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


Kit Coming Soon! We are in the process of assembling all the items shown here into a new WOWKit.
Please check back here to see the new WOWKit when it arrives.


HO-Scale Life Like Proto 2000 E8/9 shown with the shell on.
To start off this install, we must first remove the shell from the chassis. 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 and ladders as you lift off the shell so they don't break.

Shown with the shell off. Remove the two screws highlighted above in red and remove the original lighting board all the wiring connected to it.
Set aside these screws for future use. Carefully disconnect the front headlight assembly and remove and discard the original 1.5 V bulb.
For this installation, it will be replaced with a LED inserted into the original housing.

In this installation, the unit has a blue wire shown that connected the right track pickup to the motor and then back to the track.
This connection 'loop' must be removed to isolate the motor. The outgoing motor lead and the original track pick up lead will be connected directly to the motherboard.

The locomotive shown with the wire leads trimmed and lighting board removed.

As the lighting board itself will not be reused, trim off the components as highlighted above in red to create a flat platform for the installation of the new TCS components.

Reinstall the modified lighting board as shown above.

Using double sided foam tape, secure the AS-MB2 NC onto the lighting board, feeding the rear track pick up leads through the board to ease the routing.


Next, using the same double sided foam tape, mount the KA3 as shown next to the board.

WIth these components installed, insert the 25mm X 14mm WOWsound speaker into the UNIV-SH4-C
enclosure and using double sided foam tape, mount this assembly onto the front of the frame facing up as below.

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.

Insert the LED into the original light holder and solder these wire leads to the motherboard according to the included wiring diagram.

TCS motherboards include on board current limit resistors for LED use. There is no need to apply external resistors for LED use. 

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 Life Like Proto 2000 E8/9 Locomotive 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.
