2, 24 volt wires coming from the condenser to the the furnace with no “C” connection I have a mobile home furnace. This furnace only has a 4 wire connection terminal, G,W,R,Y. I also have a condensing unit outside with the 24 volt 2 wires coming to the furnace. I know I connect one to Y, but I don’t know what to connect the other wire to? Yes my furnace is AC ready.enter image description hereenter image description here

    Can you post photos of the inside of the furnace's wiring compartment? What make and model is said furnace, for that matter? – ThreePhaseEel May 2 at 22:58

It's the grey wire in the thermostat wire bundle

According to the wiring diagram posted for your furnace, the C wire should be the grey wire in the thermostat wiring area of your furnace. So, you should just be able to connect to that.
