Throttle problem help

Hello everyone. I am literally stuck on my tundra I don't know what to do. I wired a front camera a few months ago and since then I've been stuck. I used a drill bit to make a hole so I can take the wire from the engine to the cabin. (The same where the engine harness comes in from) after that I disconnected the accelerator pedal plug to wrap the wire around it, plugged it back in, wired the camera to the headunit started the truck, pressed the pedal when I was backing up and it didn't engage until I was past half way, the check engine light came on. Things I've done
Brand new Accelerator pedal (nothing)
Checked all fuses (nothing)
Showed it to someone and they're telling me I need a new ecm
I've attached the codes from TechStream

 

Why would you touch the accelerator wires? I don't recall seeing anything about that when I installed my frac unit.

 

Idk what I was thinking at that moment
