This makes wiring a lot easier as when you want to connect to a wire that is already in the car, let's say to the cigarette lighter, you can just slot in the new wire and put the cigarette lighter wire into the other slot of the scotchlok and use pliers to push down the metal contactor and close the plastic cover over so that the metal contactor is not exposed.


That's it!

Also, another use of this is when you want to re-line a connection of an item in your car, but it has an adaptor going into it, you can cut the existing wire, and put it into the outer slot of the scotchlok, 3/4 of the way in(so that there isn't an open wire at the other end) and put the new wire into the first slot then close the metal contactor.

Enjoy! :)
