    Ok so the tactrix cable says the code is specifically my fuel pump controller... NOW I'm tryin to buy it from local parts store and it looks different. When I googled "wrx fuel pump controller" a squared looking relay pops up, but the part number at the store is a round shaped relay. Very different... Can someone help me out by posting a picture of what exactly I should be looking for?

    Fuel Pump Controller Removal Procedure

    Fuel Pump Controller

    REMOVAL

    1. Disconnect (-) battery cable (pic. 1)
    2. Remove Rear Quarter Trim Passenger Side
    3. Disconnect the connector from control unit (Pic.2)
    4. Remove Fuel Pump Control unit (Pic. 3)

    Sorry the pictures are kinda crappy but this is what i found, itll probably make more sense when your actually looking at the thing. R&R time is 1.4 btw.

    This is getting frustrating, my fpc doesn't look like the one on the diagram, so its hard for me to distinguish where I should be checking voltage.. I'm definitely not a wiring person, so I've been looking for something exactly like mine to figure it out.. and I have no idea how to post pictures from my phone so I can get better help

    B - Black
    BY - Black n Yellow (mostly black with a yellow line)
    LgR - Light Green and red
    VW - Violet and White
    BW - Black and White
    BOr - Black and Orange

    If you need the fuel relay and pump assy. colors just let me know sorry for the confusion
