slekjr, you could "hot-wire" the Loksound decoder in:winki: . after looking at your pic, i don't see the black wire

, if there IS a black wire connected to the circuit board, hotwiring the sound decoder in will be quite easy:thumb: , if i AM seeing right, and there is NO black wire connected to the circuit board, that tells me that the motor is grounded to the frame:frowns: . what you would have to do in that case is isolate the motor from touching ANY metal on the frame:winki: .
i have a Decoder/Sound Decoder install thread that will help if the motor IS touching the frame:winki: . look at the install done by Dan Raitz, you would install the sound decoder MUCH in the same way he shows the decoder install:thumb: . he uses a chipboard, you will connect the wires, and set yours up the same way, only your Loksound decoder will not be a chipboard. you can find the tutorial here:

the wire setup for your(any) decoder/sound decoder is like this:
orange wire = right side of motor
yellow wire = backup light
black wire = left side of trucks
gray wire = left side of motor
white wire = headlight
blue wire = common wire for BOTH, the headlight and tail light:winki:
red wire = right side of trucks
i hope this helps:winki: . :deano: -Deano
