People who have jdm engine harness on us fd3s plz help
 
I have jdm harness on my car, the only difference is the blue connector.
I have read threads how to solve this problem and it is easy you have to use 12possition connector from jdm harness to 10 possition and let 2 brown wires out.
My problem is with fuel temp sensor.
In the us wiring schematic the fuel temp sensor is connected from ecu to x07-x14 and finaly to the sensor the other wire from sensor is connected direct to 4d +5v from ecu.
In my jdm harness the fuel temp sensor wire is connected to blue connector.
So it is not possible to work.
Have anyone other problem with jdm harness and fuel temp sensor

I swapped the different connector from my US harness and matched wire colors. it runs (rich) and I only had to leave one wire out. (brown and something)

Do you have pfc?
If yes check the volt on fuel temp sensor is it correct?

I answer my qustion myself.
I check out the blue connector and the white connector from jdm harness.
The brown yellow wire who all let out is the fuel temp sensor !!!!!!!.
On us and eu cars this wire go throw the white connector x14.
So there are 2 solutions:
1)Cut the wire 1u from yellow connector on ecu and rewire it to brown yellow.
2)pick out the brown yellow wire with the pin from blue connector and plug it into white connector in the same possition were the us ,eu model have the same wire.The jdm harness didnt use this position is empty.

Thats all

That would explain the error code! Stupid me using all stock components. That's what happens when I hurry.
