No big deal, but no body can explain its purpose. It’s not a factory mess up cause the wire coming out of the harness has to match the connector of this wire, Where usually a wire comes out of the harness and goes straight to the sending unit. I can state that the car has not been messed with before. If the picture loaded, this is the wire. I’ll try it with and without, I’m bringing it up cause this is some forgotten mopar thing that nobody knew about, even the experts.
