I am replacing my heater core in 68 camaro and on the top of the heater box on the inside of the car, there is the connection for the wires. It is actually a wire harness with a cardboard insert that gets bolted to the top of the box. Does this just sit down on the box and really doesn't connect to anything. When I unbolted the old one that did work before the heater core broke. It just pulled it right out of the box like it was not connected to anything. But the heater did work. This piece has a couple of spring on it. I hope I explained it right. Thanks, Erik
