The first shell includes a plurality of exit holes and the second shell includes a first connection interface and a second connection interface. The wiring harness passes through at least one of the plurality of exit holes of the first shell and includes at least one data communication line coupled to the first connection interface and at least one power line coupled to the second connection interface. ## Claims ### Claim 1 A surrogate component, comprising: a body, comprising, a first shell comprising a first end wall; a first plurality of side walls coupled to the first end wall, wherein the first end wall and the first plurality of side walls define a cavity; a first coupling edge defined by a distal end of each of the first plurality of side walls; and a plurality of exit holes; and a second shell coupled to the first shell, wherein the second shell comprises a first connection interface; a second connection interface; a second end wall, comprising at least two openings, wherein the first connection interface is located at one of the at least two openings, and wherein the second connection interface is located at another of the at least two openings; a second plurality of side walls coupled to the second end wall; and a second coupling edge defined by a distal end of each of the second plurality of side walls, wherein the second coupling edge corresponds with the first coupling edge; and a wiring harness, comprising: at least one data communication line coupled to the first connection interface and passing through one of the plurality of exit holes; and at least one power line coupled to the second connection interface and passing through the one of the plurality of exit holes, wherein an intermediate wall extends between at least two of the second plurality of side walls and defines a first cavity and a second cavity, wherein the first and second connection interfaces are located in the second cavity, and wherein the first cavity comprises a shunt circuit, wherein the at least one power line comprises a first portion that couples to a first terminal of the shunt circuit, and a second portion that couples to a second terminal of the shunt circuit. ### Claim 2 (depends on 1) The surrogate component of claim 1, wherein the first end wall comprises at least one of the plurality of exit holes. ### Claim 3 (depends on 2) The surrogate component of claim 2, wherein each of the first plurality of side walls comprises at least one of the plurality of exit holes. ### Claim 4 (depends on 1) The surrogate component of claim 1, wherein at least one of the first plurality of side walls comprises at least one of the plurality of exit holes. ### Claim 5 (depends on 1) The surrogate component of claim 1, further comprising a grommet located at each of the plurality of exit holes. ### Claim 6 (depends on 1) The surrogate component of claim 1, wherein the second connection interface comprises a power connector. ### Claim 7 (depends on 6) The surrogate component of claim 6, wherein the power connector is a female connector. ### Claim 8 (depends on 6) The surrogate component of claim 6, wherein the power connector is compliant with MIL-STD-38999. ### Claim 9 (depends on 1) The surrogate component of claim 1, wherein the first connection interface comprises a plurality of data-receiving contact pads positioned to face outwardly with respect to the second end wall. ### Claim 10 (depends on 9) The surrogate component of claim 9, wherein at least a portion of the plurality of data-receiving contact pads are linearly-aligned on the second end wall. ### Claim 11 (depends on 1) The surrogate component of claim 1, wherein the second cavity comprises potting. ### Claim 12 A test system, comprising: an electrically-powered machine comprising a battery compartment and a plurality of electrical footprints, wherein each of the plurality of electrical footprints comprise a power interface and a data interface; a surrogate component comprising a body including a first shell having a plurality of exit holes and a second shell coupled to the first shell, wherein the second shell includes a first connection interface and a second connection interface, and a wiring harness including at least one data communication line coupled to the first connection interface and passing through one of the plurality of exit holes, and at least one power line coupled to the second connection interface and passing through the one of the plurality of exit holes, wherein the surrogate component is located within the battery compartment, and wherein the first and second connection interfaces are coupled to one of the plurality of electrical footprints; one or more batteries located within the battery compartment, wherein each of the one or more batteries is coupled to a different one of the other plurality of electrical footprints, wherein the surrogate component has a size and shape common to each of the one or more batteries; and a data acquisition device coupled to a distal end of the wiring harness. ### Claim 13 (depends on 12) The test system of claim 12, further comprising a power supply that delivers power to the machine via the wiring harness while concurrently receiving diagnostic power data from the machine via the surrogate component.
