This is a rare Volvo 240 dash switch / knob in excellent condition. Complete with the harness. No wear on the knob. I believe this is a fader switch that goes in between your rear speakers and the radio. It was an accessory that was installed when the customer had Volvo sound rear speakers installed. Came out of an 85 240 GL. Note that there was 2 different versions of this knob between early and late cars. This is not a normal volume knob, this specifically turns left and right from a center position. There is one cut wire with a crimp connector on it. I have no idea what it went to but I show a picture of it. Will be shipped safely.
