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
