Data System UCF21

Im trying to figure out where this data System plugs into the harness at. Any help?

you have to take out the glove box and it'll be right there.

I saw a few boxes but not sure which one is it, Is there something I have to unplug? I suppose I will figure it out once my datasystem gets here.

there is a full write up on CL including pics and stuff

im sorry but im new to this whole thing whats CL?
