Fuel Pump won't turn off. Too Rich.

Here's the thread with the info.

To add to that info, I'll explain a bit more in RB-specific detail.During the install guide, you are to connect a Black/Pink wire from the ECU to a wire of the same color coming from/to the fuse box I believe. I CANNOT find this wire. I figured if I just connect it directly to the proper connection on the relay, it should work but even though the fuel pump will turn on, it won't stop if ignition is at "ON" position and it runs so ungodly rich. I really need to move the car so any help would be appreciated. Thanks.

the black/pink wire is in the RT FT corner in a brown plug next to a grey plug. You may need to remove the battery to get to it. The wire is the GROUND FOR THE FUEL PUMP RELAY. The ECU controls ground for the pump, not power.

Yeah, I found that and connected it. Still the same result. I believe the relay is not getting power or something because I can make the pump turn on my touch a wire from the battery to the bottom left connection (with some other wire connected in the relay I think, just forgot what). I'll run more tests tomorrow and clear up alot of stuff hopefully.
