Red solder heat shrink connectors. Rated for 18-22awg. Makes joining common pixel wiring together. Simply strip both wires, place them into the connector so that they overlap the solder portion in the middle and heat it up to both melt the solder and shrink the tubing around your wiring. Recommend using a smaller heat gun or butane torch to better direct the heat on the target area.
