keyless remote programming DLC location on 99 Olds Aurora

Hello. I'm new to the forum and I'm replacing a lost keyless remote on my '99 Olds Aurora. I know the keyless entry system worked as of a week ago (before I lost the remote). I have the instructions for programming the keyless entry, but the problem is the connector underneath the dirver's side dashboard is not a DLC. The connector is labled ATS and has only six pins in one row. Does anyone know of another another location for the DLC on a '99 Olds Aurora?

Thanks in advance.

It is located under left side of dash near the steering column. You may have to lay on your back on the floor to see it. It will have 2 rows of 8 slots the top of the DLC is wider than the bottom. Hope this helps
