On the EF/EL XR6, Ghia and NF/NL, the end of the adjustable intermittent wiper stalk pulls off to reveal a small ring with a set of contacts that obviously varies in resistance as it's turned, with two wires coming off it.

I'm looking for this whole assembly with short pieces of wire left hanging from the ring. I don't need the grey cover that goes over it, only the internals.

Hoping someone may have one lying around!

EDIT: Got one thanks to snap0964
