a plurality of power lines configured to connect at least a first node and a second node to negative and positive terminals of a vehicle battery; and
a filter connected to the power lines, the filter being configured to:
attract a first portion of a PLC signal to the negative terminal prior to reaching the second node, the PLC signal being output to the power lines from the first node; and
pass a second portion of the PLC signal to the power lines for continued transmission to the second node
wherein the filter is configured to connect in parallel with the first and second nodes to the power lines; and
wherein:
the filter includes first, second, third, and fourth jumpers configured to connect the filter to the power lines, the first and third jumpers being configured to connect to the positive terminal, the second and fourth jumpers being configured to connect to the negative terminal; and
the filter is configured to attract the first portion from the first jumper to the second jumper and to pass the second portion from the first jumper to the third jumper.
