That ecu is a plug and play for an 04 wrx. Your voltage should be in the 12 volt range. Make sure you jumped the correct four wires across the jumper block. They jump up and down and not side to side. Recheck all your plugs to the ecu for any fubars there.

Btw, the carberry won't flash to an 04 up ecu because the flash method is different.
