, posted Mon 4 Aug 21:36  
Hello.
Our 9520 died today and my husband took down the thermostat w/o looking at the wiring placement. We are trying to install our new thermostat, which is a Honeywell 7400. We have six wires. Any help or advice is appreciated.

The safest thing to do is remove the panel to your indoor unit to verify the color = terminal combination. If you guess wrong you can damage a fuse or transformer.
Is this a heatpump? The make and model of your outdoor unit can help determine this if you do not know.
