Put in a furnace this winter. Its an older TRANE forced air #blu120E936B1. Had to cut line from outside air conditining unit to get it in. Now trying to get te air going and am having trobles with the wiring. The colors aren't matching up to what it says on the inside panel and are different to te wires from the thrmostat. I simply need to see the connection diagram going to a low voltage thermosta.t
