Digging in to the dash wiring today with the ultimate goal of installing my new stereo equipment. The previous owner(s) of my van seem to have gotten pretty creative in the past. There is the remnants of an alarm system as well as a very questionable previous stereo install. In the wake of all this I found a few connectors which are not, well... connected. Perhaps the brain trust here can help be identify them.

It looks as thought the grey plug in the background attaches to the yellow unit in the foreground. Anyone know what this is? (located above and to the left of the doghouse)
