EGT harness? do you have an aftermarket up-pipe? or no EGT anymore??

I'm not 100% on that FYI

There are three plugs there. The large one connects to the engine harness, the 4 pin one goes to the front O2 sensor, and the 2 pin one goes to the factory EGT sensor.

One a side note the large section of harness coming out of the firewall behind your turbo is kind of out of place too. It looks like it could get melted on the turbo heat shield. That section of harness needs to turn down at about 6 o'clock, run along the frame rail (under where the cruise control module would have been from the factory), then it should run up in front of the shock tower to where those plugs are mounted.

boost control solenoid is the one at the bottom of the circle with the white clip in it
edit: it belongs behind that black bracket attached to the strut tower, which in turn is missing the rubber grommet and bolt to hold it in place
