Which relay is missing?

Truck is a 2020 AC off road. I already had the cargo lamps relay populated, and I believe the other two are for the heated seats and heated mirrors...

But what about the 4th one on the bottom? What is the factory function, and if I don't have that feature can I expect the wiring for it to still be in place?

 

To answer my own question, maybe, there was a post here with a photo where this relay is labelled as "STEERING HTR Relay", which I assume to mean a heated steering wheel? I wasn't aware this was an option, nor have I yet come across it in a wiring diagram.

Yup, and because there's no pins there's no wiring to use. It's blank. Pull out the others to see what I mean.

4runner got heated steering wheel laaaaaaaate in production, 2022, tacoma never got it in 3rd gen.

 

Thanks. I didn't stick my head far enough in there to notice it wasn't populated. Anyone know some relay terminals that would fit in there, should I want to use the space for something else?
