speaker wires broke off circuit board,not sure where they go !

[ewing railroad]

i bought a bachmann sound decoder on ebay new in package, in the process of installation in my tender,i broke the speaker wires loose from the circuit board. i soldered them back where i thought they went, but when tested, the  engine moved but no sound. is it color coded, or is there a wiring diagram to go by? the decoder has AE 32019 on it. thanks for any advice.

You better recheck the brand of that decoder.

Bachmann does not market a "sound decoder" such as you are describing.

this is a bachmann 8 pin decoder with speaker it say bachmann on the pcb as well as the package it came in,this was a factory replacement item to give dcc and sound to dcc ready trains like my 2-6-0 mogul. all worked briefly until the wiring came loose, and i am not sure where the 2  speaker wires go? i tried going by color but no luck.HELP!   Jim
