Start by spreading the shell and lifting it off of the engine.

Next, remove the wiring from the original lighting board, and remove the lighting board from the engine.

Next, install the motherboard in place of the original lighting board, and mount the 35mm speaker in its housing and install the housing between the frame.

Attach the wires from the speaker and locomotive to the motherboard in accordance with the wiring diagram provided with the motherboard.

With the motherboard and speaker wired in you can install the WOW121-Diesel decoder, replace the shell, and re-attach the front coupler.

Your WOWSound installation is complete and ready to run.

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.
