My HKS Type-1 TT came with instructions for a 2002 WRX so I found the 2002 ecu pinouts off of Ravensblade's website and cross-referenced the two so I could figure out what Subaru called each sensor.

Then I looked up those sensors on the STi ecu pinout (ECM I/O Signal) from the manual I downloaded and got this:

Plug B134:

Pin 23 = I RPM

Plug B135:

Pin 5 = B 12v Switched (ignition)
Pin 19 = U 12v Constant
Pin 27 = S Speed Sensor

Plug B136:

Pin 3 = #4 injector
Pin 4 = #3 injector
Pin 5 = #2 injector
Pin 6 = #1 injector
Pin 22 = P (FCD)
Pin 23 = P (AFR) Air/ Fuel

Plug B137:

Pin 1 = E Ground


*There was no TPS info for our ECU I guess because we are drive by wire but this was the info on the diagram for the STi:

Plug B136:

Pin 18 = Main; Fully Closed = 0.6; Fully Open = 3.96
Pin 29 = Sub; Fully Closed = 1.48; Fully Open = 4.17
