The first picture attached below where I circled the connector on the left, is you data link connector. This is what you plug your scan tool into in order to communicate with the vehicle.
As for the black box, I can't place that. It looks like a factory wiring harness so I don't think it is an aftermarket part but again, I can't place it. Is there a part number or any number on the box itself?
Worst case we can just unplug it and see what doesn't work or what codes it sets and that will tell us what it is. However, you only want to do this if you can clear the codes. It won't hurt anything because once you plug it back in and cycle the key all the codes will go stored but lets see if there are number on it first. Thanks
