Hello from moldy Seattle!

Another one for the W.O.O.F.'s:

Just noticed the label on the LuxDrive 20 mA Variable Resistors indicate plus / in and minus / out legs. Never looked that closely.
If wired into an AV switch, I would assume the plus / in leg is the upstream side, and the minus / out leg is closest to the AV switch.

Is that correct?

If not installed as described above, would they work as intended?

Thanks, as always, and best regards,
