Hi,
As far as the connectors are concerned, check to make sure none of the wires have been pulled out or damaged, check the condition of the connector pins, and make sure it is fully attached.
Now, I didn't realize nothing in the rear was working. All the rear lights have a common ground as I mentioned above. I didn't suspect this because I was thinking park lights and brake lights worked. Since nothing works, we need to go straight to the ground first.
Go to any of the light sockets. Locate the black wire at the connector and check it for continuity to ground. The ground (G100) is located at the lefthand front of the engine compartment, on the upper radiator support.
