Hi, I went through heater core replacement in my 78 280z. Heater core is controlled by mechanical valve with no vacuum hoses attached. This car has aftermarket installed AC. I see a copper wire that hangs in there and I do not know where to connect it. It looks like copper tube with sensor at the end of it. I see that it starts from the coil under the heater core and goes out long enough to reach the valve. It was just hanging around when I started replacement. I think I need to connect it somewhere but I do not know where to stick it . Can someone help me with this?
