How does this disconnect? Fog light connector

[TRACTION]

Anyone know how to disconnect this type of electrical connector? It's the factory connector for a Dodge 2500 fog light harness.

I'm sure it's probably easy when you know the trick but I just can't get it to separate. The red tab that seems like it should be the key to separating the two halves moves back and forth.

The two wires that originally came out the left side of the connector (first picture) were clipped off.

Anyone? Thanks for the help.

You are correct. The red tab IS the key....I just dont remember if its push, or pull....

From the looks of things, it seems that it gets pushed IN....

I posted the same inquiry on Cummins Forum and the key is to slide the red tab back then push down the black stepped part just underneath it. Viola! It's unlocked. I have fog lights again. :wings:
