Hi All, I am new here so be gentle. I am working on a Great Wall V200, 4D20 diesel, and for the life of me I cannot locate a copy of the wiring Diagram! I have tried dealers in Tasmania and mainland Australia! and not one of them seems to want to help me, Does any one here able to point me in the right direction please, I have a PO255 code and I am only getting 2.5 volts out of the ECU to the injectors, yes I have checked th wiring as far as continuety goes . The manufacturer in their wisdom have changed the color of the wires at the fuse box and it is confusing me , WHERE can I obtain a wiring diagram? kind regards Marcus.
