Flow Series 5V wiring harness has 4 outputs by default, but can be increased by adding 2-to-1 Flow Series splitters (1 splitter equals one additional connection). Each connection is a 3-pin JST connector designed to connect to most 3-pin addressable Flow Series LED components. The power end of the wiring harness features a 2-pin Deutsch connector to easily connect to our voltage regulators. No more soldering together the wiring harness and voltage regulator! The wiring harness also has 1 female 3-pin JST wiring connector for the controller to connect to. DO NOT try to run power separately to the controller, it receives power directly from the wiring harness.
