Ive been searching around but has anybody done it? ive got a good running mk3 only thing that i wanna do is to swap to my mkv chassis. any help would be appreciated
Not to derail your thread but you are proposing to swap a stock normally aspirated OBD I 12V into a Mk5 chassis? That seems a bit strange at best.
At a minimum you should be considering converting that motor to OBD II to make the harness integration a bit more seemless. That OBD I block you have will not have any of the side provisions for the engine mount locations either. Seriously you might want to consider a more modern motor (AFP and up). You can have the motor mount provision, drive by wire and OBD II so things go together a bit smoother for you. Not impossible but I'm baffled as to why you would even consider this.
