Hello everyone, I just scored a BLI AT&SF 3751 class 4-8-4 on eBay and it has the old QSI Quantum Sound system circa 2004 which sounds like crap. I want to remove it and install a Soundtraxx Tasinumi2 decoder so I need to know the wiring designations for the BLI six-pin harness from the tender to the locomotive. Can anyone give me the Motor +, Motor -, Headlight common, etc... Thanks for helping. John
