A/C Stopped after disconnected heater

I was afraid I broke the circuit some where. The 5 wires I have at the furnace end are red,white,blue,green and yellow.This group seems to run to the lower unit of the AC where there is a plate with 4 screws which has the green,white blue and yellow wire attached to,the red wire is cut about 6" from the plate,there is no tail ends hanging down or attached to any screws.The back of the thermostat has 6 wires soldered to the back and a lot heavier gauge then the regular stat wires.It has all the colors plus a grey wire. Coming out of the wall are 10 wires two sets of the common colors.After looking at the diagrams and then looking at what the factory installed they do not match by a long shot. I have romax wires running on the bottom of the ceiling joists with the ceiling board stapled to the joists making a sandwich of 2 110 lines. Is there any way to run wires from the tstat just to the AC.Also I do not get any power readings on any of the stat lines.
