Hello, this is about part 'Module - Smart Data Link - Ford (JG9Z-14F642-A' the ODb port. Took car to a stereo shop that wanted better access under dash so took the OBD off and disconnected the back wire array from the unit. The guy said two pins were flattened down but he didn't think he did it, but he straightened them back up and plugged the unit back in to the harness. At that point the car went bad, windows, interior lights, dash , blinkers, everything stopped but the engine would start. They checked all fuses but were baffled so I had to have it towed to a dealer. who told me the pins didn't match and someone must have replaced the unit. I had watched the guy---it had not been replaced, he just unplugged it, straightened out then pins and plugged it back. The dealer told me no---the pins didn't match (Im guessing he meant all the males to the females for my model) and that they lied to me or I was wrong. I felt like he was calling me a liar. They charged me 400 dollars and now I see I can get it from ebay for 20 bucks, darn. My question is---could the original port be something that ford had a lot of and flattened two pins to make it work until they ran out of them? Or maybe it was designed for more than one model but the factory commonly flattened two pins depending on the car? The dealer thinks Im a liar, and at the very least the stereo guy should have to ay if those pins were supposed to be flat.
