Default 2007 Radiator Support Wiring Harness Help!

Hey guys, I've been having difficulties with a 2007 WRX in our shop I have been going back and forth with our local Subaru dealership but they haven't been able to figure out what the spare wire we have goes to. We have the rain sensor already hooked up as shown in the picture as well as both horns, but there's a 4th wire that comes off that which we have no idea what it goes to and we are assuming it must mount to that empty bracket next to the horn. Does anyone on here happen to know what it is?

What do you mean by rain sensor? Like rain sensing wiper sensor?

Could it be the OAT Sensor plug?

*Edit*: Looks like it's plug F102, Keyless Entry Buzzer. P/N Confirms it. Has the same bracket, your buzzer is missing. OE P/N: 88021SA001
