1st goes to your TCU.
2nd is the ECU power relay.
3rd is the body harness connector. Fuel pump is connected to that one. Not 100% on this one cause it has been a year.

Transmission control unit. The steel box where your clutch pedal should be.

The plug with 7 pins running towards the back of the car is the EVAP harness, goes to a plug under the rear deck and then into the trunk for fuel temp sensor (in the tank), MAP-BARO sensor, and EVAP purge (under the car, mounted to the canister). You do not need any of it, it's all for OBD-II monitoring. Remove the entire harness as well as the canister and all related parts if you want.
