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 BL2 shown prior to installation.
To start this install, gently pulling outwards along each side of the frame releasing the shell out from the small button on each side as highlighted above in red
and then lift the shell off of the frame. Take care with the handrails as you lift off the shell so they don't break.

The Life Like Proto 2000 shown with out the shell.

To remove the original lighting board, remove two screws located in the front left and rear right corner as highlight above in red, then also remove the black plastic
platform located underneath it by removing the the two screws on either side towards the rear as highlighted in blue. Save these later screws for reinstallation of
this piece.

Shown with the lighting board and platform removed. Trim, tin or lengthen the wires as necessary.
Remove and discard the original 1.5 V bulbs. For this installation, it will be replaced with a LEDs inserted into the original housing.



Locate the metal tab on top of the engine and solder a connection point to the front of it as highlighted above in red, then solder on a wire lead.
This will become one side of the motor lead.

Reinstall the plastic platform piece with the screws you saved and using double sided foam tape, mount the AS-MB2 NC to it.
Make sure it is positioned front to rear in a way to allow room for the speaker installation behind it.

Using the same tape, mount the KA4 keep Alive® to the frame in front of the AS-MB2 NC and solder the wire leads according to the included wiring diagram.

Likewise, with the 35mm X 16mm WOWSound speaker inserted into the UNIV-SH1-C enclosure, mount this assembly to the frame and solder the wire leads
to the motherboard according to the included wiring diagram.
NOTE:
In this installation, the open fans on the roof have loose fan blades. In order to prevent vibration which could compromise the sound quality,
we recommend that you add a small drop of model glue to the junction of the fan blades and spindle to prevent this movement.

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.

With these three components installed, mount the LEDs in the original bulbs locations. Solder these new leads to the AS-MB2 NC 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.

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 2000 BL2 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.
