don’t know, but not reving past 2k is likely caused by a missing TPS signal.
Did you record a data log before swapping harnesses?
These aftermarket harness have grlund wires that differ from OEM. Best to call tucked.

If you could post pictures of the wires that would help. I would keep your oem harness around just in case. Did it have any cel before you swapped them and what brand harness is it ?
