This is a solderless, clamping connector is intended to be used with our 12V Addressable LED Light Strip. To use, simply cut off some of the clear insulation on the LED strip to reveal the gold contacts, insert into the connector, and pinch to close. The connector will pierce each contact, providing a robust and long lasting connection. The wires on the other side can be swapped around by prying up that side of the connector and simply sliding out each wire and sliding them back in to the desired channels. That way you can keep your power & ground colors consistent and remove the redundant data line if you choose not to use it!
