We offer a complete brake controller installation kit, part # ETBC7, that includes all components needed to install a 7-way connector on your vehicle, including connector, wiring and circuit breakers. This kit requires that your vehicle have a working 4-way flat connector installed already (such as the one that will be on the custom harness you are considering). I have included an installation video for the ETBC7 and also an FAQ article on wiring a brake controller.
