If you are talking about the black wire you laid across the wiring schematic, that's your original battery cable that went between the positive battery post and the starter solenoid.
I think the problem is all that extra wiring octopus you have in there makes it hard to understand.
Cut back the electrical tape on your mystery wire to see if it is a wire, or a cable.
