What is this electrical connector for?

[Desert Fox]

There is an electrical connector with a single brown wire running to it on the passenger side by where the air intake goes into the fender.
Any idea what this connects to?

The vehicle is a 2005 Sport edition 4Runner V6 AT

Connector

On my 03 Ltd it's for the horn for the alarm. It's wedged between the inner passenger fender and the intake air box. Looks like it is even the same color.
Hard to get a clear picture, tight space. This is looking down along the inner side of the fender.

Excellent, thank you for checking

I don't think I have an alarm installed
