The power antenna wire provides power for a retractable antenna. Not sure why they even still include that. Can’t remember the last power retractable antenna I saw.

Haha I just got this truck, but my 2001 pathfinder had an extending antenna. The crutchfield instructions mention using it but I'm going to leave it off then. Thanks!

No need to worry about the wire in the Frontier. I wondered the same at first, if not having the wire hooked up was going to affect reception, but the wire on that adapter corresponds to an empty terminal on the truck plug it connects to, so it truly does not matter. It is for retractable antennas as mentioned above. I yanked the wire out of mine. I don't listen to radio really ever anyways but the few times I have turned it on for whatever reason, it has worked just fine.

I figured once I actually removed the dash I would see the wire was unused haha, thanks for the final confirmation, tucked the wire away

My oldest son used to have a 06 VW Jetta Wolfsburg that had a amplified antenna and needed that particular wire connected.

That was what I was concerned about. However it turns out I didn't even need the adapter whatsoever. Mine already had the regular radio connection and was plug and play with the alpine unit.
