Can anyone point me to a source for an OBD port / wiring dongle for my Jaguar XJ8 2000? I believe the port in the car is damaged and causing read problems (i.e. the mechanic's expensive OBD reader can read the monitors but the standard OBD reader can not) I want to make sure there are not physical wiring issues with it before I go messing with the software. Yes, I did have the original ECM cloned a while back and didn't discover the problem until I went to get the car smogged. Also the facia wiring harness was replace 2 years ago and I have had no electrical problems what so ever - car runs great and everything works great except for this issue. Any help or education would be appreciated.
