Bussed Electrical Centers (BECs) have been around for a number of years, and have been one of the key technologies used to reduce splices in a harness. A BEC is actually an enclosed matrix of metal stampings that creates a structured and organized means to interconnect wires and route power to where it is needed. It also provides a logical place for fuses, relays, diodes and other devices. In contrast, a conventional wiring harness requires individual splices to supply each load. That means the supply wire is stripped of insulation, a mechanical splice, cut-lead and possibly a device is attached, then it is taped over to insulate it.

daisychain (bused interface) A means of connecting a number of devices to a controller, or, used as a verb, to connect by this means. A cable is connected from the controller to the nearest of the devices and then a separate cable connects the first unit to the second and the process is repeated as required. This allows a single connector on the controller to serve a variable number of devices. It also reduces cable cost and eases installation when several devices have to be connected. The IEEE-488 and SCSI interfaces are suitable for this sort of connection.
