I have a OBD2 plug pig tail and I and trying to put a USB plug on the opposite end and I cant find for the life of me a detailed schematic, don't get me wrong I can find a diagram on pinoutguide.com but it all looks like a foreign language to me I can't figure out what wire goes to what color or pin. I guess I'm asking if someone has a photo or something I could see so I can figure that out, yes I'm that guy who just looks at the pics in a book and doesn't read the articles, haha . If anyone has one or could lead me in the right direction to one and no you don't need to leave bread crumbs, I swear I can take directions...I appreciate your time...
