Your original connectors look like this when you remove the wires. These are the ones which have the wires connected on the top.
When you replace them your far better off replacing them with the ones Nino suggested. I've just done these ones recently.
I was fortunate enough to have someone show me how to do the first one but they are very simple once you know how.
Simply remove one wire at a time from the original connect, cut it at the previously crimped point and strip the wire to show 5mm or so of wire. Then crimp the new connector onto the wire. Once connected push the wire into the connector until you hear it clip in then remove the next wire and start again. A good tip that I was given was to always mark the original connector as you remove each wire because its very easy to get mixed up with where your up to.
