You should be able to follow the FSM engine electrical diagrams and get it to work.. I did. Are you using a WRX harness (USDM) or a JDM one? That might play a role in your confusion. AFAIR, the fuel pump/ relay diagrams are spot on..and dont go only by wire color.. but go by pin location. We have the same car so it should be the same (but I am using an 02 motor and my origional tranny). Also something that would have helped me is as you move/ pin plugs, MAKE SURE YOU GOT THE PLUG OREINTATED CORRECTLY! Afterwards I actually colored all the bottoms black to make sure of this when re-checking. Make sure you got the top up.. I misplaced 4 wires that way.. so far. Label and recheck. Its tedious, but it will save you headache!!
