This should be a simple problem but I cannot figure out how to open up this electrical connection correctly. Looks like it slides open but not easily. Tried pushing down on the top, sliding, even prying apart. I know there is a simple trick to opening but it is beyond me. It goes to one of the seat switches. Everything ready to be put back in the car if I can get the hot and ground leads inside of this simple plug. I can rebuild engines but this is way beyond my mechanical abilities! Any help would be appreciated, thanks!
