There is a special prong removal tool you can get or you can use a very slim jewelers screw driver to push the prong's clip in.

The problem I had when I replaced my turn signal wiring harness was that the Ford replacement harness had different colored wires than the original. It made it hard to get it working properly. It got it working but I had some funny moments like when I put the turn signal on and the horn started honking

In case it is not obvious I should mention that you push on the wire forcing the pin forward towards the end of the cup (to release the grip it has on the cup) and then push the pin's clip thingy inwards forcing it towards the wire and then pull the wire out of the cup. I hope this makes sense.
