I have a degree in electronics, I just can't find a wiring diagram for this system, I know the orange wire coming off of the condensor is the 24v and the blue wire coming off of the contact switch activates the switch, I pretty sure the other blue wire is to activate the fan motor inside on the furnance, so I just need to know what the red=RC ,the White=y coming from the thermostat get attached there are only three wires to be hooked up.

Anyway you can snap a picture ?Most of the time it's just 2 wires that hook up at outside unit

This system has a 220v step down to 24v transformer, the orange wire is coming from that, this woill provide the 24v for the contact switch, the contact switch has 2 blues coming off from it one is to engage the the compressor and the other to activate the furnance fan. the three wires coming from the furnance is a red=rc, white=y and a blue which is attached to a yellow wire which goes to the fan control box, the red wire is attached to the rc in the thermostat and the white is attached to the y from the thermostat. I hope this gives you a better description to help me. If I had a wiring diagram of this I could figure it out myself.

Thank You!
