With milling of the frame, they have been able to utilize a AS-MB2 NC, KA4 Keep Alive® and UNIV-SH4-C WOWSound kit.

These items are available in the WDK-ATL-7 which was used for this installation.

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

Life Like Proto 2000 SD45 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, squeeze the shell along each side and lift the shell off of the frame.
Take care to release the handrails as you lift off the shell so they don't break.



Shown with the shell off.

To allow a space for the motherboard and speaker, the frame must be milled square above the original brush bracket as highlighted above to keep all the
components below the original top of the frame.

Remove and discard the original 1.5 V bulbs. For this installation, it will be replaced with a LEDs inserted into the original housing.

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

With the frame milled, using double sided foam tape, mount the AS-MB2 NC to the frame and using hot melt glue, mount the KA4 to the front as shown.
With the 25mm X 14mm WOWSound speaker inserted into the UNIV-SH4-C, mount this assembly using the same tape to the frame.

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, LED and speaker leads to the motherboard according to the included wiring diagram.

You can now plug in the WOW121 Diesel Decoder.

Lastly, in order to keep the wires neat and prevent possible shorts, lace the wires into a bundle using lacing cord, which is a wax impregnated string 
used for wire bundling and making harnesses. There are many choices of lacing cord available from Digikey www.digikey.com
We use part number 802534B BK032-ND

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 SD45 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.
