Hello all, I have a Nissan Pathfinder 2007 and this is the radio: https://drive.google.com/open?id=0B6bpkLLF0N9VdWVsbm9iWHdRMFVsUHVIMFY1VHRzZnJ2MS13 I've bought a touch screen radio from ebay and their cable connections does not match. This is the original radio's connectors: https://drive.google.com/open?id=0B6bpkLLF0N9VRzFINHFtMDZlNVZpNUFBNldNQk5rYlBqcFlj (There's another one, in the next picture.) I can make some sort of a arrangement with the connections but there's an issue.. I don't know what each pin of the connectors of the radio do/mean. There's one connector that has 12 pins,only 5 pins are used, but it seems to do nothing since the radio functions all the same without it. https://drive.google.com/file/d/0B6bpkLLF0N9VNlZBaU5CaTI2N2R6QUNBUnZOMkZVU3FQanJz/view?usp=sharing
