Heated Seats Prewired?

[ToyYoda 4Runner]

I'm looking at installing some heated seats in my 2008 T4R Sport Edition. After looking over where I plan on putting switches and wiring it all up, I ran into a couple interesting things. In the fuse box, there is a fuse assigned for heated seats. As I recall, Sport Editions did not have the option of heated seats?

In the center console, as well as underneath the drivers seat (I didn't look under the passenger seat...), I found an unused plug/connector. After quite a bit of googling, I haven't found what they could be for. Is it possible that the seats might be pre-wired for heated seats?

I will post pictures when I get a chance.

This has been covered, but I'm pretty sure Toyota uses 1 wiring harness. It has everything included, so it should be wired, they would definitely be using the same fuse box for all.

I think that unused plug is for on board air. I recall a thread on here about someone wiriing up their seat heaters to the factory fuse and it included them running new wires on the factory connectors coming from the fuse box. They followed the wire from the fuse box to in the car. When it got in the car, the wire didn't continue.

I can't find the thread, but yes.. there is some wiring pre-done for heated seats

I believe a relay or fuse is missing; my understanding was that the pre-wiring ended near the driver fuse panel though and not all the way to the seat

Here are the pictures of my 4Runner. One of the pictures is under the seat showing the unused connector. The other two are, of course, of the fuse/relay box under the hood showing the fuse for the heated seats already installed from the factory.
