Installing WOW sound with a MB2 motherboard and WOW121 sound system. Info from TCS shows a different motherboard then what is actually in our tender (which has just recently been purchased new). The problem we have: the wire colours are different from the wiring diagram  from TCS. The wiring from our motherboard reads front to rear; black, green, red, red, yellow, brown; the two on the rear are red and orange. Any information that would match the wiring from the Bachmann  motherboard to the TCS MB2 motherboard would be greatly appreciated. Thank you from a mere mortal - Rick

Thank you for your input. Is there no way to decipher which wires are what?

Do that with your ohm meter. Do a continuity check. If you need to, put a paint dot on each wire using MRR paint. Follow the NMRA color code.
I have done that a few times. Also, keep the NMRA wiring code nearby.

The Bachmann PC boards I have seen have labelling on them.
