The ALDL should be under the dash to the right of the steering column. It may or may not have a cover on it.

:iagree:
I know in my 85 if you are sitting in the drivers seat, It will be right in front of your right knee. Take a peek under there.....

If you can't see the port it may have come loose and is dangling behind the hush panel. That's where I found mine. :)

I have a 90 base convertible...I found my diagnostic post (it had a cover on it) but there is only one row pins...all the pics I have seen, the ALDL (I assume is the same thing) has 2 rows? Help!!!
