reversing valve neutral

Del

Hi-

  Just had to bypass a bad control on a 20 year old York heat pump to get it to work in A/C only mode......replaced the integrated thermostat etc.  Homeowners have a newer natural gas furnace so they don't need the heat pump.  Anyway, I have the reversing valve energized through O terminal but I wasn't sure where to complete the circuit.  I have the contactor energized through high pressure switch and Y and C off the furnace control board like usual.  Can I use the C on the furnace to complete the reversing valve circuit, or will that interfere with the contactor operation?  I'm pretty sure it won't, but I just want to be sure.  Thanks.

The "C" that runs the condenser is the one you would use, and I assume that's the one on the furnace.
