How can you tell which ones you have? Is it a different bracket?

JEzus people the resources are ALL OVER THE NET and this site. You can pull a connecter and tell the difference by looking at the plug, hell you can even tell the difference by looking at the back of the pigtail.

Old style = square connectors

New style = oval connectors (square with rounded corners)

The new style are pretty oval to me. Square with rounded corners, wouldn't it be more rectangle with rounded corners? lol.

If it takes a small screwdriver or something sharp to move the metal wire so the plug can come off, you have the old style, and yes, square. Or if it takes a miracle for the connector not to break when you pull them off, you have the old style.

If all you have to do is press a tab with your thumb and pull= new style.

Yeah I didn't wanna say oval and have him think its a perfectly round oval or something lol

When I put my new style connectors on they are so new I have to use a flat screwdriver to press the little tab, plus my thumb wouldn't be able to get to most of those connectors lol
