Hello, I am looking for a diagram with cables from OBD to the controller, I am doing a swap and I only have a piece of installation from the engine to the ECU controller, I bought an OBD plug with cables, Pin 9 plus black and red and Pin 4-5, I have two black and blue grounds already connected, also connected I have Pin 7, a purple cable to the controller, the program still doesn't connect to the engine, there are other cables left in the plug, Pin 13 green and white, Pin 12 green and red, Pin 8 blue and beige, Pin 11 purple and blue, apparently the rest of the cables go to the cruise control? or does it have to be connected for the OBD to work?
