To start off this install, we must first remove the front and rear couplers screws as indicated above and remove their housings.
With the couplers removed gently pull apart the shell at the two ends and along the sides and lift the shell off of the frame. 
Take care with the handrails as you lift off the shell so they don't break.

Solder the KA4 Keep Alive® to the AS-MB2 motherboard and using hot melt glue, securing it to the inside top of the front of the shell.
Next, insert the 32mm speaker plug into one side of the speaker ports. This plug is included in your kit and we have found this greatly enhances the sound quality of your locomotive.

With this done, solder the speaker wire leads to the AS-MB2 motherboard and place the 32mm speaker in the other port within the frame, securing it with hot glue. 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.

Lastly, in order to keep the wires neat and prevent possible shorts, lace the wires into a bundle using lacing cord.
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 Atlas H-24-66 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. 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

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.

Lacing Cord

In order to keep the wires neat and prevent possible shorts, we recommend lacing the wires into a bundle using lacing cord. Lacing cord 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
