Balanceing tap with six wire"s?

Yes i check the extra wire with a volt meter and it reads 0.0 volts,the plug has
six slots and six wires,i tryed to change the plug with a hyperion tap but the end of
the plug wires on the evo pack are to small.Do i need to change the plug end to
fit the hyperion tap,or do i buy a different tap plug?
