Continuous 12V in Aux Pin on 7-Pin Round Connector?

Question:

Does the Aux pin in a 7-pin round pin connector have Key-On continuous 12V? If not the Aux pin, any other pin have Key-On continuous 12V?

When using the Pollak Heavy-Duty, 7-Pole, Round Pin, Trailer Wiring Connector - Trailer End # PK11700 the key on 12V power depends on the vehicle. Some vehicles will have a keyed 12V power and others will have a constant 12V that runs even when the key isn't present.

That 12V power will be on that center Auxiliary power pin. The running light circuit will also technically have 12V keyed power.
