Which USB cable do I need to read codes using my lap top?
Very rough running car here...
Thanks! |
It would not be unusual to find the ALDL connector stuffed up behind the drivers side hush panel. If the cover "Diagnostic Connection" is missing there would only be the connector visible and it's mounted towards the rear edge of the drivers side hush panel right of the column. It could easily be overlooked I'd guess if you didn't know where you were looking.
In this post you can see it's approximate location to the hush panel edge. It's a tough find for many:
