JDM vs. USDM ecu (yellow plug)

The entire wiring of this car has been a nightmare from the very beginning.
So it has new wiring, strong ground, both knock sensors work, the connection to the ecu is very tight and strong. I'm just out of options it seems.

It has jdm engine, usdm wiring and ecu, with one jdm sensor and one usdm sensor (i guess)
ok so you say if engine knock is bad enough it'll set off CEL anyway, do you have any idea of how I could check excessive knock?
