A reconfigurable connector system for distributing power between an input power source and a cable harness connector having M cable harness terminals includes an energy center module (ECM) and a connecting adapter. The ECM has a module housing, a PCB having more than M pin holes, a plurality of e-fuses connected with the pin holes, a controller connected with the e-fuses, and an input connector connected to the controller and/or the e-fuses. The connecting adapter has a body with first and second sides and M bridging adapters within the body. Each bridging adapter includes a first connection point accessible from the first side and configured to be directly connectable with a cable harness terminal, one or more second connection points accessible from the second side and configured to be connectable with a pin hole, and a busbar connecting the first connection point with the one or more second connection points.
