Based off your previous comments I'd check the continuity of the wires with a multi meter. Even then I'd pay close attention to the pins and maybe even rewire it with a thicker wire, making sure to leave some slack so it. Lmk if that helps ๐Ÿ‘

I did use thicker wire. I was at orilleys just now and my christmas lights are back again. What i noted is power is slightly lacking via ktuner yet when im on Ktune acceleration suffers. Im wondering if my waste gate is faulty. Im about to swap out my spark plugs note my ktune. Pics attached

I, too, was just recently afflicted by P0035. Repairing a green wire seems to have fixed the issue for me, so I figured I would tack-on my experience here. I have a '20 Si sedan w/ ~38k miles.

Was leaving work one cold evening, got the car under load and got the Christmas tree dash. Scanner revealed the following codes:
  • P0035 -- Turbo bypass control solenoid valve circuit high voltage (Permanent + Temp)
  • U0416 -- VSA Brake Actuator Malfunction
  • U0416:68 -- VSA System Malfunction
Tested my battery with a multimeter and it was low (11.8v), and it was still my original OEM battery so I figured I would start there. But the issue persisted, at which point, I dug in and found all the threads here and on Facebook, etc.

I found this YouTube vid super helpful with diagnosing and fixing, so check it out. I had just been messing around on the back side of the engine (oil temp/pressure sensor wire routing) the prior weekend, so strongly suspected the green wire behind the engine by the oil cap. Sure enough, when I pulled off the electrical tape (no visible damage from the outside) I found this, just like the OP:

The YouTube vid helped with connector disassembly, but one tip on pulling out the pins is that you need to apply pressure with a small flathead or similar right here so the metal can clear a square protrusion in the plastic plug body:

I tried to give the short green wire still attached to the pin as much of a mechanical connection to the pigtail extension as I could before I soldered, but there wasn't much of the green wire left to work with:

Finally, here is the plug re-assembled and pigtails soldered back to the harness wires before heat shrink + sheathing:
