I want to install an LED and I need to splice into a wire.How exactly do you connect a new wire to an old wire? Do I cut it? Then what? Solder?
They make a part which wraps around the old wire clamps together with a connection for the new wire you want to add. See an auto part store.
1 way you can do it is cut the wire, peel both ends and use a 3 way butt connector. hook the wire you cut in the butt connector and the wire your wanting to run in the end that,s open.
Soldering is by far the best method of connecting two wires. You can use the small clamp/connector methods, but they are not very permanent and tend to corrode and lose connection if ever exposed to elements or anything. If you can solder (or even try) -do it.
You can use a Scotch Block Electrical Connector, or Scotch-Lok if you put them on correctly you won't have any trouble with the connection, these are fast connectors. If they are going to be outside in the dirt and rain, heat shrink wrap them, you should really always do that but especially out in the weather.
