What is this connection?

What connection is this? It is on the left rear of the Tahoe (99 2 Door).

barn doors, tail gate? a wider picture would help. Also I see what colors on wires exactly?

My best guess would be for barn doors. Maybe for the door locks. It doesn't look like the rear defrost plug on trucks with lift gates.

I think door lock was on right side.

Door locks are on the right side. This is on the left rear. The wires are black and purple with a black connection.
