Hello, I have a 2006 F-150 FX4. It has a ruff idle and check engine light is on. When I plug my OBD2 reader into port and try to link I get ERR (error). It will not link. The reader works on my other vehicles and has worked on this truck before. There is power at the port on most pins. I don't know what pin should have power, ground etc.. I also don't have the owners manual that tells you what fuse is what. Does any body have this diagram?
Any help would be great!!!!
