Alpine RUX Knob pin connections?

Well, I tried to take it apart. Took the two side screws off, and the PCB had another screw holding it down, but also it looked like I would need to roll the sheet metal body, too, to get it out of there. I don't want to risk mangling it up.



I'll just try a regular RJ11 cable when I get the system installed. If it doesn't work, I'll try reversing one end. If all that fails, I'll cough up the 25 bux for a new knob/cable.


BTW, I check the impedance...through two of the outside pins, it rolls from 0Ω to about 20KΩ. I guess it only utilizes two pins.
