    Need help wiring a thermostat
    Hi,

    I have a ruud central air unit with an eclectric furnace and a honeywell thermostat. There are four wires a blue which has power, a white, red and black. The red and black seem to be for the ac unit as they were not hooked up over the winter and the furnace worked just fine. Now I cannot figure out where to connect the red and black wires. Blue is connected to the B terminal and white is connected to G.
