I am looking to modify all the factory harnesses for my 2003 Evo but I do not know what connector goes where. I purchased this harness used for my 4g63. Where can I find the diagram that shows all the connectors from tail lights to body to engine to headlights ?

Thank you

you can go to evoscan and download the wiring diagram. However you wont see pics of the connectors youll have to probably take pics of another evo.
