From the attached pdf's you should be able to establish the throttle body pin outs

Isn’t that an 06-07 throttle body as it has the MAP sensor attached? 08+ don’t have it there as far as I know. Might not make a difference for the pinout anyway.

The diagrams come from the MY08 WRXSTI workshop manual
The 08 throttle body has the map sensor attached




MY06-07 items

But the OP appears to have the earlier throttle body. I might be wrong but I’ve got two e throttles sitting on the spares shelf, one with the MAP sensor mount and one without because I was sent a later one by mistake that has no mount for the MAP sensor.

My post edited above

The EJ255 WRX Hatch throttle body does not have the map sensor attached due to the different inlet manifold arrangement.

Interesting. Do you happen to know when or if they did indeed move the sensor off the throttle body then? I’m curious what this one I have is actually from.
