what was cut out? what do I need to wire in? explanations? diagrams? suggestions?
(i have a s4 n/a right now.)

That is the body harness plug in the ECU that was cut out. Why I don’t know why anyone would cut that. You should have that clip in your car already :-)

The clip in the last pic you are wondering where it went. That is one of the emissions plugs that goes up to the right along the wall way up in there. Stick your head up with a flash light and stair up there you will see a few connectors that’s the one. The clip does look like a ECU clip but none of the ECU clips come out of the harness in that location and that far back on the harness from the motor side ECU clips.

awesome, nice, good, great. Does anyone have a diagram of the s4 n/a wiring and the s5 t2 wiring so I know what goes where when and how?

that body harness plug that I already should have in my car doesn't fit into that connection on the t2 ecu. soo... do I need to use that already cut clip and splice in my old body harness connection so it plugs into the new ecu.
