9HX and 9HZ engine wiring loom compatibility

[Giuseppe]

Is the engine wiring loom from a 9HZ engine compatible with a 9HX engine? because i'm having problems finding a 9HX with the bosch edc19c34 ecu wiring loom

They have different part numbers and markings, so they are not the same. Obviously the 9HZ engine has greater power and a particle filter, so there will be additional connections for the extra sensors like the differential pressure sensor(s) for example, but I can't advise on any other differences.
