1990 Buick Lesabre

I Have A Problem With My 1990 Buick. I Hope Someone Out There Has A Solution. I Bought A Scanner To Tell Me What Was Wrong With The Engine. I Can't Find The Aldl{assembly Line
Dianostic Link}; Or, Alcl{assembly Line Communication Link}
To Hook The Scanner Up.
I Checked The Normal Places Where The Link Should Be, But, No
Luck! Can Someone Suggest Other Places To Look?
This Is Really Turning Into A Major Operation; It Should Have Been Simple But, Apparently Not.
I Really Need Help Please!! This Is My My Only Means Of Transportation To Work.
Thank You In Advance For Any Help!!

It's Behind The Ash Tray, At The Bottom Of The Dash.
