Search for ReubenH's thread on Single Turbo Legacy conversion. He's got a step by step guide and near the bottom of the first page is the pinout diagram that you need. Its got the 4-plug Legacy, Legacy TT, WRX pinouts and so you match yours up to the WRX one and start swapping.

Tip #1: Label every single wire in your ecu with its pinout number i.e. A12, B7 etc based on which plug its in.

Tip#2: Once you've switched all the wires over, you need a diode between two of the power wires on the ECU. I can't remember which ones but if you power it up and turn the key on, use a multimeter to check all the ones that should have +12v. One of them will be at 0v so you need to put a diode (or just directly splice a wire) to one of the ignition switched 12v feeds. This will turn your fuel pump on.

Tip #3: Make sure you've got the ignition wires to the ignitor around the right way. All that happens if you get these wrong is it idles rough and backfires when you give it some throttle.

Thats all I can think of for now. Also, once its done, get a chip for the ECU as the 4-plug WRX ECU's give sfa power and don't feel grunty until you chip them and run 14psi
