I was doing some remodeling and a wire that I thought didn't go anywhere was actually connected to my outdoor unit. And of course, I didn't write down how it was wired since I was positive the wire wasn't connected anymore thinking it went to an old secondary thermostat. I have a Bryant heat pump, blower/furnace with e-heat and thermostat.

The thermostat and blower are still connected as follows:
Thermostat - blower
W - white wire
Y
G - gray wire
R - red wire
O/W2
C - brown wire

The wires coming inside are connected to C, Y, R, O. How would they connect to my thermostat/furnace wiring.

Thank you in advance

Thank you for your response. I tried the simplest of connections and connected C-C, Y-Y, R-R, O/W2-O. The fan inside did not turn on in auto but does in manual and the compressor outside still does not turn on for heat or cool.

Any thoughts?
