Likely depends upon your model, year, etc. but here's a start.

It’s a 1980 911 SC.

Thanks for the link.

Is there a diagram on one of the surfaces?

Mine were soldered on, which seemed weird. Yours has a bunch of rosin flux all over it too... Hmm.


IIRC, it's a panel mount 100K logarithmic potentiometer with an on/off switch.

Log pots are pretty common in audio applications, so not hard to find one if you need to.. Some might even accept the factory knob/cap.


RoninLB posted this current flow diagram, post #8 in this thread: Intermittent wipers on an early 911.

E38 is the intermittent pot.
