that black thing is a box. LOL
Not sure yet, but there is a 7-pin something in this pic:

look at the bottom at the 7 pin deal - it appears to be related to lighting.
So you physically traced the ALDL link leads back to the ECM?

this says an orange wire and a wht/blk wire go to the aldl from the ecm
If that is good, this may sound dumb but check the ECM# and make sure it is for your car. I've seen wrong chips installed and the car runs. you may also want to see if the pins are physically ok, maybe one of them is bent/broken.
