2004 - 2007 USDM STi

Please send the complete body harness (at least from the dash to the headlights) from the WRX/STi. The harness will unplug in one large piece, DO NOT CUT ANY WIRES. You will also unplug and include the fuel pump controller (FPC) that would be located in the trunk of the car. We need the silver module only. Leave what is physically on the engine untouched. If you have any questions, please ask before removing the harness

Fuel Pump Controller


If you do not have a Fuel Pump Controller, iWire can supply one.
