Potato Head

Hello, I have a Lennox Merit series 10ACC outdoor air conditioning condensing unit that I have to disconnect, move then reconnect as I am installing a new patio. What things should I be concerned about as a DIY job? There are four connections: power, vapor line, liquid line and thermostat line. The power and thermostat lines look simple enough, but I'm concerned about the vapor and liquid. Any insight would be helpful. Thanks!

I replaced a fully functional home thermostat with a new digital thermostat from Honeywell. Now neither my heating nor my air conditioning works. I have 5 wires white (W), red (R), green (G), blue (C) and yellow (Y). When I cross a wire with red nothing powers up, so its not the thermostat: for example, crossing red with white should turn on the heating. My breaker box shows all the breakers are enabled. I see no breakers or switches on or near the heating or air conditioning units. I've also reset all the GFCI outlets. What could I be missing? I hate to have to call an HVAC expert out here to kick a breaker or something silly. This has to be something simple. HELP!!
