I need some help.

My sister in law got into the two wires (red and white) that trigger the
condenser unit to run. My mother in law had a repairman out during the
winter. He disconnected the trigger wires from the inside unit.

Now, I hope to run new wiring (inside some conduit) from inside to outside,
but I don't know where to attach the two wires. I called the company that
did it, but they want to charge to come reconnect those wires.

What I can see, inside there are four wires coming from the thermostat. A
red, white, yellow, green. They attach to a printed circuit board. Does
the red n white from inside also attach to the outside? Or maybe, I need to
take the cover off of the circuit board and there are more terminals there?

This is a very old carrier crusader, venting from the side.

Thanks for any help
Scott
