So I tried diagnosing whether the code 41 issue is due to the brown wiring.
I removed the intstrument cluster / panel as well as the ECU and routed the brown wire.
Please take a look at photos:
The brown wire behind the instrument cluster, that comes from the noise supressor, was spliced into two brown wires (there was electrical tape around it). One of the brown wires seems to feed back into the instrument cluster connecter.
The other brown wire I believe feeds into some other connecter, which I think eventually routes into the ECU.
So Im thinking the wiring might be okay.
I did notice something odd when pulling cluster - please see image - there is a black / white wire that seems soldered onto the back, under some black tape. is this correct?
Another thing I did notice - I did pull the alarm system and the wiring is kind of janky. One of the red wires that goes into the ECU (your diagram says fuel injector power) is for some reason has an additonal wired spliced, going into a larger gauge wire (white / green) under dash. Any reason why someone would do this nonsense?

ALSO - the interior dome light is missing. this wont affect anything important, will it? I think I noticed a connecter with a white and brown wire (drivers side) leading up to another connecter than should go into the dome light. doesnt matter if its not connected?
