Help! I'm trying to wire in an STi 3 air temp sensor into my Power FC on my MY98/v4 WRX. The Power FC sockets and the ECU plug format is the same for both WRX and STi, with a crucial difference - the WRX v3/4 did not use an air temp sensor, therefore I cannot work out which pin to insert the air temp sensor into. Presumably once it's done it should show the air temp display on the Commander but at the moment I cannot get it to show up at all. THe only thing I can think of is that I'm putting it on the wrong pin - what would appear to be pin 19 of 22 on the bottom-most plug. The other two plugs (middle and top) have loads of empty pins but the bottom one has only one space, at 19/22.

Help! I cannot find an actual STi 3/4 pinout anywhere, only for a WRX.

Sorted! Got a link to a page in the US with just about every wiring diagram there is:

NorthUrsalia.com: Wiring Diagrams And ECU Pinouts

Got a v3 and v4 STi pinout off that, and my air temp sensor is now working! For future reference if anyone else is doing this mod (adding an STi temp sensor to a v4 WRX or Turbo to be displayed on a Power FC) you want the middle of the three plugs, which is the smallest and it's the top right pin as you look at the ECU, which was labelled as pin 1 on the pinout I saw.
