7 way trailer plug

how do you disconnect the plug?
The one on the bottom

 

First pull it out of the frame, its not the normal type of push pin that holds it in, if you pull on it or get some dykes under it you can pop it out.

For the connector itself if memory serves you rotate then slide the gray part that holds them together. If you look at the grooves in the sides of the gray piece you can figure out which way it needs to move. It is a little tricky getting them apart.

 

I figured it out tonight. You have to grab the white connector first and pull down and then you can squeeze the black connector to release the latch and then pull the plug. Thanks for the reply.
