*****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 website. Please review and select 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, B-MB4 Motherboard with built in Keep Alive™ and UNIV-SH4-C WOWSpeaker kit.
HO-Scale Life Like Proto 2000 E8/9 shown with the shell on.
To start off this install, we must first remove the front and rear coupler screws 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 and ladders as you lift off the shell so they don't break.
Shown with the shell off. Remove the screw highlighted above in red and remove the original lighting board all the wiring connected to it.
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.
With the original lighting board removed, Tap and drill new screw mounting holes to align with the mounting hole locations on the B-MB4 motherboard.
Using small nylon spacers, mount the B-MB4 to the frame as shown above. Next, with the 35mm X 16mm WOWsound speaker inserted into the UNIV-SH4-C
enclosure, using double sided foam tape, mount this assembly onto the front of the frame facing up.
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.
Solder the motor, track, speaker and lighting wires to the B-MB4 according to the included wiring diagram. In this installation,
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!
Important Soldering Tip
Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.
TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.
You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775
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.
