Melted O² Sensor?

The downstream Oxygen Sensor melted together when I went to change the sensor. The problem is I can't see the vehicle side connection clearly enough to determine what wire goes where and connects to what wire on the sensor wire harness. I bought a replacement repair kit, STANDARD S-1933, which matches the OE kit 05013971AA to repair the connector.

Question,

Do any of your mechanics have a manufacturer schematic showing the connection setup?

My schematic (Haynes) only shows the vehicle side but does not show the connection to the oxygen sensor. Had this happen once before on a 1998 dodge grand caravan but on the upstream o² when it contacted the manifold. Fortunately, then the vehicle side was viewable enough to get the wires in place. The sensor wires are as follows: 2 white, 1 black, 1 gray. I know there are 2 grounds (body ground and sensor ground), 1 sensor power, 1 other positive but have no clue what connection goes where. I need help on this, and this a disability vehicle has to get exhaust pipes welded too so everything is getting done at one time in the outdoors (no shop here) setting.
