12V Electrical wiring - wire nuts vs crimp connections

Good point about not having enough slack in the wire to do much with. You get your one chance and that's it. So a way around that is to use your one chance to add some wire.

Then use the new wire added on to connect to the light or whatever, with the connection type of choice. Later if need be you can afford to cut some off to do the replacement.

EDIT- I see the above poster slid in there with the same idea! :)
