Wiring diagrams?
 

Hi, i've been having a few running problems lately which i'm slowly getting to the bottom of. However the main problem i'm having now is that I can't connect my scanner to read the fault codes, it used to connect fine.
I have a feeling its to do with the wiring but i'm having trouble tracing them to test for continuity.
Has anyone got wiring diagrams for the diagnostic port and ecu they can send me, or links to them please???

120 or 180?

120 mate
