I am trying to hook up a Honeywell RTH2501B Programmable thermostat. The thermostat I am removeing is a Trane BAYSEN008B. The Trane is wired #1 yellow #2 green #3 Black #4 Red #5 white. Where do the wires go on the Honeywell? I tried Black to O/B, Yellow to Y Red to R
Green to G and White to W/AUX. That didn't work. What am I doing wrong?

Transpose wiring diagram for old GE/Trane. Use old Trane/GE from the list
