I have moved my furnace and A/C unit into my attic. I need the high side gauge readings and the low side readings. I also need to know where to connect the two wires from the compressor to the furnace thermostat contact block.

If you moved the inside unit without disconnecting the refrigerant lines then the charge should be the same as it always was. If you disconnected them you will have to evacuate the system. Then recharge and check the final charge using superheat if it is not a TXV unit. or subcooling if it is a TXV unit.
