by de-pin do you mean remove the wires from the connector?
if so, you will see a piece that looks like a puzzle piece on one side of the connector, you use a tiny screwdriver to pop that piece up (not all the way out though) or it may also be a white piece inside the connector depending on what end you are dealing with, but that piece locks everything in and must be released. once you do that you need a very tiny flathead screwdriver (i use am eyeglass screwdriver) and will have to release little clips inside the connector on each wire and remove them one at a time. if you are having to use force then something is wrong, it doesn't take much to remove them.
if that's not what you meant by de-pin, then I just wasted both our time, lol
