How to reattach ABS wires into connector

Hi all, a few months back my ABS light came on and I noticed the front wheel ABS sensor cables had detached from the connector as shown:

The connector as you can see in the picture has a clip mechanism which you press in to detach it from the plug that it connects to, and I thought perhaps that also holds the wires in place, although it does not. Any advice would be much appreciated.

I was able to protect mine before it broke, but you can see other folks doing repairs after the fact (in the first thread the guy actually salvaged the existing connector pins).

If you are asking how do the wires break? Just by turning the handlebars back and forth enough times -- the wires have no stress release, so they bend right at the connector crimp, and eventually the metal fatigues and breaks.
I think the issue wasn't a lack of slack for movement, but where the movement actually occurred... The wires have a thick plastic sheath all the way up to the connector, so that portion of the wire tends not to bend in favor of the fragile place where the bare wires enter the connector doing more of the bending -- so a disproportionate amount of the bending occurs where the wires are most fragile... On my bike, I just covered that portion of the wire with heat shrink tubing, so it could not bend, and now the thick plastic sheath (which is unchanged in length from stock) bends instead, distributing the bend over a longer length of wire -- so hopefully I won't have a failure.
